Limited or no connectivity

[Brembo244]

Hello
I have a Arris modem that my ISP provided.
I get the exclamation sign on my network tray icon every 5 minutes and so the internet is down.
I've tried setting the DHCP manually but still the same problem.Sometimes when I click ''Troubleshoot problems'',when the wizard almost finishes,it suddenly gets back online.
I've reseted the modem,enabled/disabled the network adapter and even installed more driver versions.I've uploaded a picture to show you how the network and sharing center looks then.
Sometimes it doesn't want to get back and the only solution is to restart.
I have Windows 7 Ultimate x86,Realtek RTL8102/8103 Family PCI-E FE adapter.
Thank you.

Try this next time it happens

type in search

ipconfig /flushdns then

ipconfig /renew.

Did it help?


Are you running "homegroup"?


Have you re-iinstall the wifi driver?

Well first of all the modem is not wireless, it's cable.

I've tried /flushdns, /renew when it wasn't working but it gave me an error(something related to DHCP, you can figure it out).
I've also tried '' netsh winsock reset catalog ''but it worked temporarily.

I have tried the same cable on a HP Compaq NX7400 Laptop with Ubuntu and sometimes it did the same thing(drop dead all of a sudden), so my first concern is that the modem is either rubbish or I might have to contact my ISP for further details.

 

[Brembo244]

I still couldn't figure this out...
Things i have tried(recap), and failed:

Resetting the modem by pushing the reset button or by unplugging it.
Installing several drivers including Vista ones for the NIC.
ipconfig /release/renew /flushdns/renew
netsh winsock reset catalog
setting IP's manually
I don't know why but it says Ipv6 Connectivity ''No internet access'' all the time.I've disabled it but it does the same.
Maybe it could be from using Bittorent clients?

It sometimes works fine for 1-2 days and sometimes it drops every 5 minutes.
I can't figure anything out, and this problem is extremely annoying because i cannot play any multiplayer games, or have a constant connection to the internet.

Thanks.

The IPv6 no connection message is correct, IPv6 works only on the LAN with Windows 7 so it always shows no connection "to the internet". Do not disable Ipv6.

I can't say what the actual problem is here but adding a router to the mix might improve things. If you can post the ipconfig /all from your machine I might be able to help you.

Try running this batch file which will reset winsock, reset the TCP/IP stack and release renew your IP.

Download Renew IP + Reset Winsock Batch File

Example shown below, I use the built in snipping tool for this.

From the info above I can see your in Romania and you aren't using a router. You seem to only be showing your WAN IP so your modem has no router functionality.

The other problem I see is that you have some sort of VM ware adaptor installed and it appears to be enabled which can cause problems. I'm not really sure what that is for but it may help to disable it because it could be causing your Unidentified issue.

The other possible problem is that you are showing quite a few 6 to 4 adaptors there which will also cause these types of problems. They also show as having a DNS assigned to them which makes no sense to me at all, "problem is in bold below".

I'm not sure how many 6 to4 adaptors are showing but if you can count them and tell me how many I can show you how to get rid of them.

There are so many problems with your ipconfig /all, I'm not sure where to start.

 

[Brembo244]

Well yes, i'm from Romania.
I'm using VMware Player, it's a sandbox program which you can use to test other Operating Systems.I still had problems before starting using that.
As for the Batch file you gave me, it works instantly when the connection drops, but it still fails after some time.
Ipv6 looks like this:

You need to post the screen shot of your ipconfig /all using the built in snipping tool.

I can't read the reposted copy, I need to be able to see how many of those 6to4 tunnel adaptors you have.

And you need to disable the VMware adaptor for testing as that can easily cause problems such as you are describing.

 

[Brembo244]

I've disabled the VMware adapters but this might sound embarassing because i dont know what the Snipping Tool is or how to use it..

Our sister Vista Forums has a tutorial on how to access/use the snipping tool. It will be just about identical in Windows 7.

here it is

 

[chev65]

Somehow your WAN ip changed from the last ipconfig you posted. It seems like your ISP uses a floating IP for it's customers.

And for some reason your Ipv6 shows DNS servers which makes no sense to me, it looks like your modem does this by default so it may be correct for your particular modem.

It looks like your VMware or a bad driver helped to create extra 6 to4 adaptors which will cause problems with your connection.

You should delate the extra adaptors by going into Device Manager, go to the view setting upper right then choose "show hidden devices" then go to the "network adaptors" , after that delate all the extra 6to4 and tunnel adaptors you see there and reboot your machine. Windows will make a new one. This should help fix the problem you are seeing.

You should also change the network location to work or home. The tutorial for this in the link below.

I have done what you said, deleted the 6to4 adapter, disabled all VMware adapters, and it is working so far.If it fails again i will let you know.
Thank you very much

We will see where this goes, it seems that either a driver or the vmware caused there to be an overload of 6to4 tunnel adaptors which is a fairly common problem. Delating them usually fixes the problem but the cause is still in question and may come back to haunt you if it's not fixed or repaired completely.

You many have a problem with the vmware because your not using a router to give it a seperate IP although it did get an IP from somewhere according to your ipconfig results.

A router would be a good investment in your case and should allow the vmware to work better.

 

[Brembo244]

OK, it didn't turn out well because aprox. after 6-7 hours it does this

 

[marsmimar]

Bummer. Hopefully chev65 will be back online in a few hours. Just out of curiosity, have you ever contacted your ISP to see if the problems are at their end?

At this point I'd say that a repair install is in order. I think those VMware adaptors somehow hosed your system or at least messed something up. This has worked a couple times in the last week.

Run the repair install and see if it finds something wrong and let it fix the problem if it finds one.

Would it do any good to try system file checker before going the repair install route?
