Opps, maybe not so unique since I just noticed an ENTIRE forum for browsers...perhaps moving this is appropriate...if so, please do. I will be reading up in there.
Its interesting because I can't find any mention of it anywhere on this site. Specifically browser connectivity is lost after a little while (guessing 7 minutes, though it may be a number of browser pages displayed trigger i went 3 hrs today) after I start browsing. If I don't start a browser, the death clock doesn't begin until I start browsing. Now, at the same time, all shares, the other machines on the network, work fine. Also if I am playing an online game, I will not have any issues. Just IE and firefox can't display pages and other programs (like updates of AVG) are soon to follow.
***Important to note this is new, the network was fine for over a week before this started a couple days ago.
I notice, when it works, net info states Homegroup - ready to connect (I am using a workgroup to connect to other machines) but last night, during a browser outage it said it was connected. I notice now it calls my workgroup a homegroup (I think is used to say workgroup)
(This problem may have started around when I tried to synchronise a folder to "always available offline", but there are other things that were done in that period of time unfortuately, all have since been undone.
System...Windows 7 7100 all updated.
Browsers IE8 and Firefox are effected (updated)
Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20)
Router Linksys Wireless 54GS running v2.04.4 - HyperWRT v1.3, Aug. 11, 2004 which works fine on all other machines even while this Windows 7 machine can't connect. I can connect to Mapped drives, computers and devices on the network but no browser activity and Win see no problems.
What I have done.
Tried disconnecting and connectig to local network in applet
Remove AVG antivirus
Remove Hardwaremonitor Pro (I was connecting to another machine to watch temps etc remotely and had to open a port which is still opened now that I remember it)
While it is fubared I have tried disable/enable the adapter (won't work)
Downloaded MSnetmonitor 3.3 but that is all Greek to me, maybe someone can guide me what to look for (I do see some "unknown" connections, but they seem normal, like netbios, and masterbrowser traffic, but that is just my guess so far)
Removed OPENdns as DNS server info I notice the router has since found the new ones again though the machine seems to have other ones in its settings. The other machines (XP home and Pro) are still set to openDNS and work fine BTW.
power management is not enabled for adapter.
I will edit more as I can remember what I did already.
A few things...something called "flow control" in the adapter applet is disabled. Any bearing on the symptoms?
Anything I can post from netmonitor to help you wizards?
Just saw this post, which is very similar Firefox Troubles
I am trying IE64 bit to see if it is immune to this. EDIT: I just noticed I can change "Home Network" to "Work". I will see if this helps, and it might since this is the way it was for weeks.
