Why does my internet connection fail intermittently?

On my laptop, my internet connection fails now and again. I'll go to a web page (Let's say Google) and I'll get page not found. I'll then sit and press F5 to refresh the page until eventually after a minute or so it'll suddenly work. All will be well for a while after that until suddenly it'll happen again.

"I was having this issue on Windows 7 with a RealTek wireless card. Reinstalling drivers for the wireless adaptor (and numerous other attempts at a solution) didn't fix the problem.

On a whim, I disabled 802.11N on the wireless adapter properties (reverted to G and B only) and it started working! My intermittent network drops (connected but no internet access) went away."

Have you tried following the openDNS guide here, to make sure it's not a DNS issue? I used to get this all the time, but since switching they've gone away.

It probably is a DNS problem, but your local DNS cache may be broken, you may not have a plug in (for some of the pages) or a problem may exist with your browser.

Don't rule out the possibility it could be hardware related. I had the same problem with my ISP provided router. Till I went out and bought my own... now problem is fixed...
