Help needed with Wifi connection which keeps dropping out.
I am using a Toshiba Satellite Pro with Windows XP Professional, Firefox, Windows Firewall, Avast antivirus, Ms Office 2003 with Outlook 2003. I have TalkTalk fast fibre broadband recently upgraded from standard broadband (about 3 weeks ago). I have no other devices connected to the internet.
About a week ago I started experiencing an intemittent wifi connection which for no obvious reason just drops out and then at no fixed timescale, reconnects without me toucking the computer. Sometimes it is down for 10 mins and the longest has been a day. During this time I cannot open any webpages or receive emails in Outlook. Mostly the wifi icon in the task bar then shows "limited or no connection" rather than it's usual "connected". The icon always shows Excellent signal strength and speed of 54Mbps. My router always has it's connected light showing. I get a message saying "The network did not assign a network address to the computer" when the connection is down. In Outlook when it will not receive emails an error message ox80040900 has said "server name cannot be found, might be temporarily down"
I have sought TalkTalk assistance with this issue who have run all their checks on my line and connection and say they cannot find any problems.. I have made no changes on my computer or with any of the lines/connections coming into the house. I have experienced no other issues at all with my computer or connections prior to this.
Whilst it appears that the problem should be with the TalkTalk service reaching my computer they say not, so I would like to check if there is anything with my computer that could be causing this issue.
Help with this will be much appreciated, thanks.
