PC using forever to connect to WiFi

[avetaas]

Whenever I try to connect to a wifi network, I simply get the error 'cannot connect' for 10-15 minutes or so, and then suddenly it works. This applies to all networks, whether it's been used before (saved for automatic connection) or not. However, as long as I don't switch networks, it connects instantly.

For example: I use the notebook at uni and bring it home, it takes forever to connect to my home network, and forever the next time I connect to the uni network. If I don't use the PC at home in between sessions, it connects instantly to the uni network the next day.

Thanks in advance.

Check and see if theres a driver update available.

Hi

If you have a profile for each then you would expect it to connect easily.

Perhaps try D, E, G. H, I and W and expect one to solve your problem.

Prego.

I would love to state which one did the trick, but honestly I have no clue. Works for now. Thank you.

Hi

So distill it down.

Use each individually.

ipconfig /flushdns

pause

ipconfig /registerdns

pause

ipconfig /release

pause

ipconfig /renew

pause

netsh int ipv6 reset reset.log

pause

nbtstat -RR

pause

netsh winsock reset catalog

Like ths....

WinKey + R   type cmd.exe  pause

A screen appears...

then use the single line commands until Voila.

I doubt it was this one though, more likely an ipconfig option.

C:\>nbtstat -rr
    NetBIOS Names Resolution and Registration Statistics
    Resolved By Broadcast     = 0
    Resolved By Name Server   = 0
    Registered By Broadcast   = 3
    Registered By Name Server = 0

If in doubt please ask.
