Hi people - first post to an excellent site. Been using your advice to sort out virus problem on my main pc with great success.
New problem - unable to get my laptop to work wirelessly for last few days. Have checked via limited start up using msconfig to ensure no trojans/spyware - then disabled windows firewall - then disabled security and finally it works.
Router is BT1800HG - broadband is with talktalk (surprisingly reliable and recently upgraded to 6Mb?) - recently reduced MTu to 1400 to overcome problem with webmail access. Using WEP - my laptop is Sony Vaio S VGN-S1XP.
Feel naked with no security - any ideas?

The only thing that comes to mind on this issue is did you just buy a new wireless phone, or any other electronic/electrical device?
That may be interfering with the signal if in close proximity.

If you are using XP Pro, try going ba in restore to a point when you knew that the wirelass LAN was working, if this resolves the issue, then check what you did after that which might have messed up the connection.

Thanks for the reply. No new phone or anything recently - tried restore (using xp professional) but it always says there have been no changes - do I have a faulty restore as well?
Why should it work ok unsecured and not using WEP? What is the WEP doing? Obviously my key is correct - 10 digit as on the base of the router.....

Did you try shutting down the router completely for 3secs then bringing it back online?

When you say disabled security what exactly do you mean??/ do you have another firewall/Antivirus/something like that???

Yes i have tried that a number of times.
I mean I have set my router to generate an unsecured wireless signal. This means any one can log on to my broadband signal.......

Most routers will allow you to limit access to certain MAC addresses - so you can achieve a measure of security with that.

I just saw a video on how to hack WEP in 10 minutes - so security is obviously a relative thing.

The best security is to shut it off when not using it.

Since it communicates without security - then either the security function is broken - or the settings aren't correct. You'll have to check both the router and the PC to determine which it is.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

Here're some other suggestions:
- ensure you have the latest firmware version for your router
- check your wireless card for the latest version of drivers
- use 26 instead of 10 on WEP
- change your channel on your router

For latest versions of firmware and drivers, the component manufacturer's websites will be useful.
