I hate those type of log files ;P....
Instance based stuff stinks.. The "TLV-11 - unrecognized OID" error is interesting but probably doesnt relate to any fault your seeing.. the wndr3700 gets it's time from NTP, so try to compare a disconnect time, to the times shown in the modem logs.

Also try to make a note of the log after each disconnect, and keep count of the counters. As long as you dont reboot the modem it should help point us somewhere :/

Default Re: My laptop causes internet connection loss

Some more observations...

The cable modem does not log anything when the dropout occurs.

The router does not seem to log anything when the dropout occurs. Although, the log seems to fill up and stop at some point so it's kind of hard to tell.

I can always access the router admin functions and the cable modem functions.

Everyone using the router loses internet connectivity.

Only my computer causes the dropout (about 2 minutes after boot).

I do not have to be using the internet to cause the dropout (although I'm sure windows 7 is online in the background).

I'm scratching my head.

Thanks,
Tony

Oh, I forgot to mention...

I can usually get internet access back by accessing the routers admin functions...going to Router Status and release/renew IP then to Basic Settings and Test. Sometimes this has to be done twice.

Again, not sure is any of this is relevant.

Thanks,
Tony

Finding this error is going to be a lot of work.

It generally sounds like there's a broadcast (coming off of your pc) that's skuppering something.

We could do a lot of changes, but it's going to be time consuming and if your a novice, you will probably be fed up.

I have a couple of things to try in the router first.
Save your settings before we begin, tho, by now you can probably set them without looking.


There is one thing that you could try that's easy and quick, this would alter your laptop and not the router. There's a tool on GRC that can disable UPNP for your windows based pc's. If the problem is UPnP based then it would stop it. This wouldnt tell us exactly what's falling over, but it might be worth doing. I keep it disabled on all of my pc's, but some games may require UPNP. The tool can turn it off and on at will, so there shouldnt be any harm in trying it first.

Here's my list of stuff we can try that will not require much effort.

1) Change RIP Direction (Advanced / LAN Setup / Rip Direction) to both, or in.
Change RIP Version to Disabled.
Reboot th e router and test it again!

If it still happens...


2) Turn off UPNP (advanced / UPNP / untick box) then Reboot router, then test.

If it still happens...

3) Give one of the pc's that works a settings for a FIXED IP, DNS, GATEWAY. Change all the settings so it doesnt request anything from DHCP, after that's done then reboot the pc and make sure all is well. Then connect your laptop and see if connectivity is lost again.

If it still happens...

4) Turn on the GuestWifi network on the router and try using your flakely trouble causing pc on the GuestNetwork. See if this causes connectivy loss on the other pc's.

If it still happens...

Then We will probably need to move into stuff like wireshark.
You shouldnt have these kinds of problems, Even when you see this stuff a lot it can take a while to figgure out the fault, and then there may be nothing you can do about it!. Hopefully a netgear bug report would get you somewhere.

Issue resolved....I think.

The one item I forgot to bring up...because I thought it could never cause a problem...is the printer. Yes, the POS HP printer.

After purchasing a new Netgear router I was searching the discussion forums to get a head start on any possible issues. Reading through until I got to one titled "My printer crashes my network" or something to that effect. Sure enough, someone had a HP networked printer that was crashing his/her network. I read through until I found their resolution...tried it on my printer and what do ya know. Network/Internet has been working for 6 hours no problems....and yes this is a record!!

I'll try to find the post/fix and re-post it here.

Thanks again to everyone that was helping!! Sorry I wasn't giving enough or the right information to help me out.

Thanks again,
Tony


I will try to change the name of this thread to reflect the problem/fix

Still tho..
One defective unit shouldnt kill the router ;P.

MtnBikeGeek - please post solution if you did in fact solve your problem. I am having almost the exact same problems with my laptop causing all internet connections in the house to be lost. I also have a HP Printer. My configuration is:

Dell Vostro V131 laptop
i5 processor
Intel 1030 Wireless N adaptor
HP D110a Printer

Well...problem NOT solved.

Today, I get a "Problem loading page" error about ever hour to two hours.

I don't believe anything changed between yesterday and today. Go figure.


Here is what I thought might fix the problem.

Today I'm at my fathers house...same problem. I get setup on his Netgear router and in 2 minutes his internet access is gone! (also a WNDR3700)

P.S. If left alone the internet access will come back in about 5 minutes.

If you go to someone elses home and they have the same router and you experience the same fault.

Then you know it's a compatability issue. It needs to be found.
