Win 7 - internet access issue

[heideway]

Hi,

I have three Windows7 machines and 1 windows XP machines on a home network. Yesterday morning all the Win7 machines indicated that they were connected via their wireless connections to the wireless router - but none had internet access. (Yellow exclamation mark shows on the tray icon - see attached screenshot).

Thinking that this was a router probelm I reset it - without any change to the win7 machines. Connecting them via the network cable connection was working fine, so I thought that it was a problem with the wireless software/hardware on the router.

However, the XP machine was (and still is) connecting fine with the router via the wireless signal. Our iPods, iPhone & an Android tablet are still connecting without any issues to the wireless and have internet connection, so this is limited to teh win 7 machines ( My laptop is on win 7 professional, the 2nd & 3rd machines are win 7 home premium x64bit.)

Additional Info:
- None of the Win 7 machines are doing automatic software updates.
- The router is a Netgear CG814WG v3 which has not had any software updates either.
- Wireless encryption details as per the "NetworkSnapshot" picture attached



Any help will be apprecaited,
Thanks Pete

Do you have windows update set to automatic updates, if so, maybe its updated the router driver for w7 recently - you could check in programs and features to see if this is the case- you could also try a system restore on one of the windows 7 machines to see if that resoves the problem - then you would be looking at an update causing the problem if the issue is fixed.

I have an xp machine on my network and the workgroup name for XP is MSHOME, so I also named the workgroups on my W7 PC and my laptop the same - could check to see your workgroup is the same name on all your PC's.

No automatic updates set for either machines or router.....

Hello,

I would consider a Firmware update for your Netgear router.

The router is a Netgear CG814WG v3 which has not had any software updates either.

Please let us know.

I have still not been able to solve thsi one. I was wondering whether anyone has had problems like this while using AVG anti-virus free - this is updated on all the affected computers.

Post# 4 - Did you go to the link I have provided you to manually download the router's firmware? After the update, I would consider to reset the router to the factory default setting, then reconfigure all fresh.

Firmware upgrade

Hi,

The link provided does not list the router - I have the CG814WGv3 which is a proprietary router for Telstra Bigpond cable. I will have to pluck up the courage and spend an hour waiting on the on the phone before I can get hold of a technician (if things go well)

Will let you know how things turn out.....
