[SOLVED] ISATAP Adapter #2 Problems

[dee_can]

Hi jc, Here is the requested zip file. Can you tell me why you want me to remove Superantispyware and Malwarebytes? Thx.

Dee, try these suggestions one at a time and let us know if there's any change with disconnections:
Plug your laptop into one of the 4 LAN ports of your router with a network cable and disconnect from your wireless network. Surf the net and see if there are any disconnects.

I plugged directly into a LAN port on my router/disconnected from my wireless and had no disconnects while using it for more than half an hour except when I closed the lid on my laptop and opened it again, but the disconnect was only for ~15 or so seconds, just long enough for the computer to wake up probably.

Go into Device manager, right click on the ISATAP device and select disable. Uncheck the box for Internet Protocol version 6 again and leave it off. these can both safely be turned off for now.

I didn't get disconnected after doing either one of the above either. The internet was quite slow, though, and took about 15 to 30 secs to open an email. That's the only thing I noticed.

If you get disconnected, click the Start Button and type Network & Sharing into the Search box. Click on the Red X in your network map and let Windows troubleshoot the problem. Write down any messages Windows gives. You can try this using only your wired connection and then again using only your wireless connection.

I switched back to wireless and waited for a few minutes but my computer didn't automatically connect, so I had to go into 'Connect to a network' and manually click on my network. This was sitting a foot away from the router. Other than that incident, I didn't have any disconnects after using the computer for awhile. Which tells me a lot, but I'll let you tell me in case I'm wrong. :grin1: I don't quite understand how I can have 'excellent' signals from the router elsewhere in the house, though, but still get disconnected. I don't have portable phones or baby monitors. I do have a microwave, but it's rarely on - does it still interfere if it's not in use?

And something else I just noticed. The router is in the den in the basement (so surrounded by cement/concrete foundation), and down here, the Xirrus program isn't picking up the same amount of neighbouring wireless waves as it was picking up when I had it on yesterday in the upstairs' part of the house, which is where I use my laptop 99.9% of the time. Looks like something I'll have to live with though.

If it's just a problem with interference I feel bad for making you guys work so hard. :embarrasment5:

Hi, Dianne.

Can you relocate the router from the basement? See How to improve your wireless network and boost its signal.

 

[dee_can]

Hi Corrine, I'm going to look into options about moving things around. I was thinking the good part about it is that the neighbours probably can't find me.:lol: Thank you for the link, I'll have a look at it.

 

[Corrine]

Although the neighbors may not be able to find you, it doesn't help that you have trouble staying connected to your network. To protect your wireless network from your neighbors, see Wireless Network Security - Prevent Hijacking, particularly the linked article, Set up a security key for a wireless network.

Hi -

Hi jc, Here is the requested zip file. Can you tell me why you want me to remove Superantispyware and Malwarebytes? Thx.

I'll be more than happy to answer any questions that have about the reasoning behind my troubleshooting methods.

I requested removal (for now - temporarily) because these apps "phone home" and it is possible that these or other "phone home" apps may be involved, but it seems unlikely. I thought process of elimination may help isolate the cause; however, Please hold off on removing the apps for now.

You have dozens of start-up items that I'm trying to ID. I was hoping the Event Viewer System log would yield clues (the EVTX file you attached), but the log is corrupted; not sure why. The error message when I try to open the EVTX log on my system:

​

I am unable to open it with Event Viewer nor other 3rd party EVTX file reading apps. It's viewable to some degree in HEX, but not very helpful.

Example: a few entries related to Networking/Internet; "Wireless Network Connection" entries (in purple); details about the entry itself (in green) don't tell us anything:

​

I recommend that you clear the System Log in the hopes that corruption-free event recording will resume.

Please run these commands. The first will provide stats on your System log; the other will clear it. Vring up an Admin CMD screen:
START | type cmd | Right-click on cmd.exe | select "Run as Administrator" | Paste -

wevtutil gli system >0 & echo ____>>0 & wevtutil gl system >>0 & start notepad 0

A Notepad will open. Please save & attach it to your next post.

Now run -

wevtutil.exe cl System

Re-run - (to get stats on 'new' System log)

echo  ** Cleared System Log ** >00 & wevtutil gli system >>00 & echo ____>>00 & wevtutil gl system >>00 & start notepad 00

Another Notepad will open; save & attach, please.

If it's just a problem with interference I feel bad for making you guys work so hard. :embarrasment5:

Anything is possible; however, WMI from the the jcgriff2 BSOD app files reports:

Signal : 99%

This was sitting a foot away from the router. Other than that incident, I didn't have any disconnects after using the computer for awhile.

Let me make sure I follow. You were a foot away from the router and your laptop was connected wirelessly, and you didn't have any disconnection problems. Is that correct? Did you still have the ISATAp adapter and IPV6 disabled? Disabling those 2 items shouldn't have any effect on your internet speeds, they actually aren't needed. You can test your internet connection speeds here. Also, try rebooting your laptop.

Concrete will most definitely cause signal loss to your laptop, but that should show up as fewer bars on your signal strength indicator, like a cell phone. You can also have a good signal (5 bars) and still have interference. It's like radio stations - your router is the radio station and your laptop is your car stereo. Even though the signal is good, you can have something interfering with the car stereo. If you move your laptop upstairs, it could be that your laptop is receiving interference from something that doesn't reach the basement. That was the point of changing your wireless channel away from the same channel your neighbor is using. It's very common, I go through it with homes and businesses all the time.

If you can run a network cable from your modem in the basement to a more central point upstairs, you could move your router upstairs... If it turns out to be a signal issue.

Thanks for explaining. I didn't know you meant temporarily.:smile9:


I've attached the two notepad texts that you requested.

After disconnecting the network cable from my laptop (in order to go wireless) the connection was broken (which I know is supposed to happen:smile9:) (showing the red x's through the network connection icon, and the other icon (local area connection?). I waited a few minutes, or so, for my computer to automatically connect to the wireless network, but it did not (and it usually does). So, I had to go into 'Connect to a network' from the Start menu, and manually connect by clicking on my name, and then the 'connect' tab (or double-clicking my name). I didn't get disconnected after that, though. I still had the ISATAP 6 and IPV6 disabled (I still have it disabled now).

If you can run a network cable from your modem in the basement to a more central point upstairs, you could move your router upstairs... If it turns out to be a signal issue.

Ok, thank you, Fred. And, thanks for those links, Corrine. D.

Dee, as a test you could try this: Re-enable IPV6 and the ISATAP adapter then connect wirelessly when you're right next to the router. Go to speedtest or surf the internet for a while and see if you still disconnect. If you don't disconnect, I'd probably blame the problem on a wireless interference issue. If you do disconnect, leave IPV6 and the ISATAP adapter disabled unless you can find the correct driver. They are both used for a new internet protocol that piggybacks on an older one and you shouldn't notice a difference w/o it.

 

[TheCyberMan]

You can identify the correct Intel wi-fi link 5100 AGN driver using the utility below:

http://www.intel.com/p/en_US/support/detect/wireless

The wired connection is fine i understand that.

Now the original xirrus screenshot i know it is deleted showed good signal where was the Laptop then was it near to the router?

If so we would need a xirrus screenshot when you use a laptop upstairs where you use it 99.9% of the time.

Agree with Fred that a lot of concrete between your router and Laptop is going to degrade the wireless signal significantly.

can i ask when your Laptop was close to the router using the wireless did it disconnect.

You do not need ipv6 enabled at all if not using ipv6.

Leave the isatap adapter disabled it is not required for normal internet connectivity using ipv4.

Do as Fred advised and test the connection with a long ethernet cable so the router is upstairs and see what the wireless signal is like then and post speedtest results.

Re-enable IPV6 and the ISATAP adapter then connect wirelessly when you're right next to the router. Go to speedtest or surf the internet for a while and see if you still disconnect. If you don't disconnect, I'd probably blame the problem on a wireless interference issue.

Fred, I re-enabled the ISATAP 6 and the IPV6 and sat the laptop about a foot from the router. When I tried to connect my wireless network, it wouldn't connect. I tried about a dozen times, and eventually copied the error msg. It finally did connect, though. I did the Speed Test, and surfed around for about 10 minutes. The laptop did not disconnect during this time.




CyberMan, I went to the Intel site via your link, and it confirmed that I have the current version of the Intel driver.

Now the original xirrus screenshot i know it is deleted showed good signal where was the Laptop then was it near to the router?

The laptop was upstairs when I took the original screenshot; so, no, it was not in front of the router.

I'll post a new Xirrus screenshot for you, taken upstairs earlier today (while my computer was connected wirelessly, upstairs away from the router). Something I noticed, I was away from the computer while the Xirrus was on, and the signal strength didn't move on the graph. When I got back to the computer, and moved the mouse around on the Xirrus page, the signal got weaker. You can see the straight line where I'm not at the computer, and then it starts to drop when I start to do something on the computer (that wasn't internet-related). This might be normal, but I thought I would mention it.

Agree with Fred that a lot of concrete between your router and Laptop is going to degrade the wireless signal significantly.

I should clarify that the concrete foundation surrounds the basement, but the floor (between the upstairs/downstairs) isn't concrete, so the concrete isn't between the router and laptop. I drew a little diagram of the layout. The laptop is practically sitting right above the router when I'm upstairs, and the floor is your basic wood floor with carpet over it. So I don't see how the concrete can block those waves. And, as you can see from the Xirrus shot, the connection is excellent when I'm upstairs. In case the print isn't readable, the blue x is the router. The green x is the laptop (hard to read, but I said that the waves are being sent up through the floor... I think). The room surrounding the blue x is concrete. Maybe TMI... :sleep2:

can i ask when your Laptop was close to the router using the wireless did it disconnect.

The only problem I had today was getting the laptop to initially connect when I was close to the router. It didn't disconnect after I finally connected, though, but I was only on for about 10/15 minutes.

Leave the isatap adapter disabled it is not required for normal internet connectivity using ipv4.

OK.

Do as Fred advised and test the connection with a long ethernet cable so the router is upstairs and see what the wireless signal is like then and post speedtest results.

I won't be able to do that right away because I don't have a long ethernet cable, but I will get one. Thanks for your input CyberMan.

Dee, go into Network & Sharing center. On the left side click Manage Wireless Networks then locate the name of your network, right click and delete it. Back in Network and Sharing, refresh the list of wireless networks available, select yours, reenter the password and save the connection.

If disabling IPV6 & ISATAP gets you a trouble free connection then keep them disabled. I would also check the wireless mode your router is using. It's broadcasting in G band, yet your laptop seems to have an N band network card, which is faster and may offer more stability. Xirus is picking up 9 different networks in your area - that's a lot. Your foundation is also shielding you from signals outside of your basement.

Hello dee_can,

I also want to point out that any barrier (carpet, wood, drywall) will degrade your wireless signal. Also, electrical interference caused by house wiring, cable and telephone will cause signal degradation as well. Also, copper water piping and such will affect it to a degree too.

When I had my computer down in my basement it was smack-dab between two wireless-N routers and it had less than stellar connection with either. I am now back in my office, which is about the same distance from one of the routers and a bit further than the other and I have a better signal connecting to the farthest one away... Both my routers are on the same floor, one in the front of the house and one in the back.

Done.:smile9:

If disabling IPV6 & ISATAP gets you a trouble free connection then keep them disabled.

I can't remember. :lol: But, I'll experiment and see what works best.

I would also check the wireless mode your router is using. It's broadcasting in G band, yet your laptop seems to have an N band network card, which is faster and may offer more stability.

Oh yeah, I see that now. I will check my router - Adding on: I checked my router, and I think it only broadcasts in g mode, so I would have to get a new router, probably.

Xirus is picking up 9 different networks in your area - that's a lot. Your foundation is also shielding you from signals outside of your basement.

Xirrus picked up 12 different networks this morning, so I can see there are a lot of interference possibilities there. Thanks, Fred.

I do see new records now. :thumbsup2: Thanks. There is a warning and some errors in the System Log. I'm not sure if I should I re-post, (was it the evtx file, event viewer)?

Hi GZ, Thanks for the information. I'm going to look into moving the router upstairs, but it's not easy to do because the 'office' is down there in the den area with the connected desktop computer on an extremely heavy (unmovable!) old refurbished military desk, but I'll figure something out, like just moving the router itself connected to a looong cable to the modem. I was actually going to forego wireless at one point and experimented with a very long cable actually ATTACHED to my laptop and the modem, er, using the laptop upstairs while the modem was downstairs. lol It got old really quickly.

To check or change your router's settings, go to its setup page by entering 192.168.0.1 into a web browser. There should be a Wireless settings tab on the top or the left of the page. I don't know your router model so I can't tell you exactly. There should be a field called 802.11 Mode and a drop down box next to it. If your router supports the N Band, choose an option that broadcasts in G & N then save your settings. You should see a description of your options next to the settings.

According to your 2 Xirus screenshots, you have an excellent signal coming in from your closest neighbor and he was on the same channel as you. Now he's on channel 5 and you're on 6. Actually, his signal was better than yours in the previous capture. The wireless standard recommends a separation of 5 channels between competing signals. It's like 2 radio stations broadcasting on nearly the same channel. When you have Auto Channel Scan enabled in your router, the router will attempt to change channels as needed for best results. If that doesn't work, you can change them manually.

Here's the simple test. If you can stay connected while you're right next to your router, but get disconnected the farther you move away then it's a wireless signal or interference issue.

 

[TheCyberMan]

This the way i see it Dee Can you internet coonectivity with no problems on a wired connection and you have reported none for your desktop so your connection to your ISP is fine.

If the router supports 802.11n then switch it as Fred has advised it may give an improvement.

1. After switching to 802.11n test your Laptop when it is close to the router and connect wirelessly for a good period of time does it disconnect?

If the answer is yes you need to replace the wireless adapter you can buy high power USB wireless adapters cheaply these days.

If no your wireless adapter is ok.

2. Router in basement surrounded by concrete is going to degrade the signal as the antennas are omnidirectinal so the signal can go in all directions so it is probable that the signal is going thru the concrete walls at some point and vices versa from Laptop.

3. Your xirrus signal shows at -53Dbm which is not great but not actually a weak signal. What i think and by the graph on xirrus which shows your signal degrade to -60Dbm is that your signal is fluctuating from stronger to a weaker signal and then back up. At some point i think your signal is degrading to -70Dbm or above and that is a weak signal and disconnects will occur and that is due to signal degredation with the router in the basement.

4. Resolutions to this:

A. If it is feasible move the router upstairs permanently to where you intend to use it and that should cure the signal problem.

B. Where you use the Laptop make sure there are no cordless phones analog or digital or dect 10 phones, baby monitors or anything that uses the 2.4Ghz frequency in use close to the Laptop as these are known to interfere with the wireless signal.

c. If moving the router is not feasible and it has to be used from the basement then you would need to buy a wireless repeater(range extender) to boost the wireless signal from the router in the basement.

You use an ipv4 ip address so ipv6 is not used leave it unchecked.

Isatap device is used in transition from ipv4 to ipv6 by businesses and is not used should leave disabled.

No amount of enabling disabling is going to help with your issue IMO.

This is a wireless signal issue plain and simple.

 

[Fred Garvin]

I think it might be best to let Dee finish up on the steps she's working on rather than inundate her with additional ones or rehash what's already been covered.

 

[TheCyberMan]

I am sorry i am just giving my opinion on whats needs to be done in order to help resolve the issue. Can be repetitive but that happens in many threads by many helpers.

Dee can please follow all the steps prior to my last post #58 once those steps are exhausted please have a look at mine any queries do not hesitate to ask.
