where did the it geeks forum area go?

[Annatar]

Posting it here because that part of the forum doesnt exist anymore. Probably because of semi computer illiterates like me asking dumb questions. Ive got a couple more so i figured id post them here till somebody tells me not to.

1. Updating the posts i made here before, im having trouble with the internet.... It works fine everytime in devon but works patchily or not at all in sheffield (to non-uk residents, the difference is about 500 miles and different ip addresses, but i didnt think that would make a difference). Different isps does not have an effect, although i havent attempted to use the same isp (telewest) that i have in devon while in sheffield.

I have just bought a wireless network card and connect to the local network fine (or at least itunes appears to be able to use it)... but often have problems when i try to use the net.
Anyone here have the faintest clue why that might be?

2. Whilst playing with this problem, i did an ipconfig/all and discovered something callled a teredo tunneling pseudo-interface. I've no idea where i picked this up, but investigation showed it was a microsoft program involved in translating between IPv4 and IPv6. The article I read then appeared to say it probably wasnt necesssary, and the microsoft summary of the program/technology was more or less incomprehensible to me. If anyone would be kind enough to interpret it, the article is at: -

http://www.microsoft.com/technet/prodtechn...ain/teredo.mspx

Specifically I'm wondering what the differences between 6 and 4 are, who uses them and do i need the program.

Thanks anyone who knows anything about either of these questions, and sorry about the little essay.
