My machine specs are as follows:
Toshiba A200-14e Laptop
CPU - Some intel Centrino Duo thingy (T2470 I think)
Memory - 2GB DDR2-800
Network Card - Realtek RTL8101 Family PCI-E Fast Ethernet NIC (NDIS 6.0)
Wireless - Wireless WiFi Link 4965AGN
Graphics - nVidia go 7300
etc, etc, etc

I recently re-instaleld the entire notebook. As most laptops it uses a hidden partition for this 'recovery' and then formats the rest of the drive and installs the OS with all the bloatware to boot.

At this point, everything worked fine. I was able to play SCII (albeit at low settings), I could do my network tasks (my job) like do sniffs on wireshark, connect to hosts via ssh/telnet, use remote desktop to servers, etc etc...

So I proceeded to start updating my notebook using windows update. Apart from it being a long and tedious process - it worked. The machine rebooted a few times, installed some more, rebooted again, and again, and again..you get the picture?

Now, everything is up to date (until next week I suppose) but I have the following networking issues:
1. My outlook keeps saying 'Connection to Microsoft Exchange has been lost' (or something like it) and then a second or so later 'The connection to Microsoft Exchange' has been restored
2. My connection to Battle.net gets dropped while in the middle of a session and it would reconnect almost immediately, but by then I'd be dropped from the server already
3. When I ssh into a host, let's say a linux server, the ssh will time out if I don't use it for a minute or two and I would have to reconnect
4. Skype messages sometimes take 5+ minutes to deliver from people on the same network as me.
5. Remote Desktop sessions time out when I've minimized it to do something else.

Basically, it seems like the networking (wired AND wireless have the same symptoms).


Has anybody else experienced this kind of problem, and were you able to sort it out? It's irritating the living daylights out of me!
 
what internet connection have you got? ISP?
What firewall have you got installed? Company and/or personal?
 
Was everything working fine before you did the update? Perhaps one of the updates messed up the networking.
 
try going back to the beginning
1. Try it out on other PC on your network (if available)

if nothing
2. remove network connections (remove TCP/IP protocol primarily)
2.1 add/configure LAN / Wireless connection again
see then

if nothing,
3. try reinstall network drivers for both network connections

if nothing,
4. try reinstalling vista

Company internet connection. It's a Cisco Router and we have a linux firewall so our personal firewalls are normally disabled since we word with a myriad of different network tools and apps.

Many people (8 or so) running the same laptops. Everything is fine.

Haven't thought of this...will try now!

I have the same symptoms at home that I have here, so I doubt it's the company network. Everything was fine before the updates, so it was definately something that went awry there. I'll try johndoe1983's advice with the protocols...
Will try this, haven't thought of the protocols....

Done, no difference.

4. try reinstalling vista
Hehe, that's a bit hectic. Hope it doesn't come to that, but if it needs to it needs to.
