Hey Folks,

Just like everyone I have the same problem with my laptop (vista home) not able to connect to internet both thru ethernet and wireslessly. It is getting really frustated. My wireless card detects the connection but its only connected to local i.e. not able to connect to internet.

My home setup as follows : WRT54G linksys router. Have 3 other laptop which uses XP PRO and they are able to connect to the internet. But the problem only lies my vista laptop (home edition). My wiresless in WEP enable either.

Well below are the methods I have tried so far since the problem has occured:
1. Disabled the IPv6
2. Tried renewing the ipconfig in command prompt (as an admin)
3. Assigned Static IP address/submet mask/default gateway
4. Assigned a diff DNS server as well
5. enabled/disabled the wireless card and rebooted - multiple times
6. uninstalled the wireless card and re-installed it
7. turned off the auto tuning as well
8. made new network connections - manually
9. Reset the cable/modem etc as well.

Any other methods or help is greatly appreciated. I have wasted soo much time in this. Planning to go XP PRO if i cant get it dissolved.

Thanks a million

Hey guys. I just registered to reply to this thread.

I am having the same issue with my HP desktop running Vista Premiere. I have Local Access only using wired ethernet connection. I have spent over 6 hours on the phone with both my ISP and HP and still no resolution. I know it is not my modem or router, as I am able to connect my 2 Mac laptops both wirelessly and directly to the modem and/or router.

From command prompt, I am unable to renew ip config, it times out, unable to reach DHCP server.

I have reset both modem and router. I have unistalled/reinstalled network card drivers. I have completed a full system restore, taking machine back to factory specs. I have disabled IPv6. My antivirus and firewall are disabled.

I am at a complete loss on what to do at this point. The most frustrating thing is that this machine was previously working and connected to the internet a week ago. Mysteriously overnight it developed this problem.

Any suggestions at this point?

Thanks

Questions:

1. When you go over to the Macs, what IP do you get when you do an IPCONFIG? Can you try hardcoding a similar IP on the HP machine?

2. Can you connect the pc directly to the modem using a wire? Does that work? If it works, that means it something with the router. If it doesn't, I think that means you have some software blocking it. Check your anti-virus software

3. Last week, when it was running, was it also on Vista?

4. Are your adapter settings set so it obtains an IP automatically?

Good luck.

running the command "netsh interface tcp set global autotuninglevel=disabled
" seems to have fixed my issue, bit early to be sure.

if you try it, you can always change back with the command
"netsh interface tcp set global autotuninglevel=normal"

googling vista autotuning brings up many other issues with this feature, so maybe worth turning off anyway.
