I get the same problem. I have my desktop connected via ethernet because my wife needs to use the internet reliably for her university homework. My pc will not use my router but seems to connect to my next door neighbour’s network with no problem. Through the wall. My laptop is hit and miss and to be honest, it winds me up so much that I very rarely use it any more. I don’t have the time or the know how to fix so I feel like I’ve wasted best part of £100. :smack:
If you’re up for some advanced troubleshooting, download Process Explorer from www.sysinternals.com
When the problem happens, open Process Explorer (best to have a shortcut on the desktop ready since your machine is presumably slow at that point), sort by CPU descending (double-click the column header), examine the process that’s chewing the CPU by double-clicking it, and look at “threads”. You should see which threads (units of execution) within the rogue explorer process are sucking up CPU time. Post the results here or in a new thread and we’ll try to help you out.

I’m assuming you’ve scanned for spyware and viruses, following the instructions in this board’s sticky, right?
