No internet access on XP computer- HELP - Fixed but I don't know why

[#1]

My better half's XP computer won't access the internet
It accesses the network and sees the other computer on it
ipconfig /all doesn't show up any problem
Putting in the IP address doesn't work either

[#2]

not switched a time block on the router?

[#3]

nope  and just to add it is connected wired

[#4]

I had this once before on an XP machine it was down to the DHCP address it had been given. Try ipconfig /renew see if that fixes it.

no effect - note it is on a fixed IP address
does this help

I had this last year... plus 3-4 virtual machines were affected.
Turned out to be internet explorer - version 6 (default) only uses 64bit encryption - so when trying to visit google (which defaults to https / SSL) IE couldn't handle the encryption / decrupt it and thus claimed it couldn't connect.
Upgraded IE (or installed a mozilla browser) and bingo... internet worked. I only noticed as my partners laptop IE worked but my other machines (inc virtuals) didn't... and hers was version 7 of IE. When I looked at the about tab I noticed the installed encryption was 128 or 256 bits (can't remember which now).
Not sure if that helps as you've not mentioned the browser but if by any chance it is IE 6, ditch it as it can't handle modern SSL.

Is your NIC (Ethernet) not missing from that list? Have you checked device manager.

[#8]

It is the first one
Device manager shows no problems
Rebooting router didn't fix it
Problem is with all browsers and tracert command

[#9]

No a loopback IF is used for localhost (127.0.0.1) unless it's the MiniPort which I doubt which is why I was asking. I may well be wrong but until told otherwise I'll remain confused.

This is from the XP diagnostics

Comparing the two I see what you mean as this looks wrong

[#11]

Fixed it
Removed the fixed IP address from the Billion 8800NL router
Rebooted computer and all now works

[#12]

Great news.

[#13]

I have posted it on the Billion Forum - lets see what comes of that
