We enabled SSID broadcase, used WPA encryption and that cured it until a lightning strike. But it didn't just die. I loaned him my older Westell and router to sniff out the 327w had been damaged. So here's what I did.
1. Set it up proper.
2. Later (months!) swapped in my DSL+router.
Try that.

I'm having some trouble with intermittent internet connections on my three computers at home. I realize this is a fairly frequent post, but i searched and couldn't find the same set of variables elsewhere and didn't want to piggyback on another forum. All three computers run xp home, my internet is dsl and i'm using a westell versalink 327W modem/router. I have an hp pavilion 750n (slighly older), a new Gateway GM5260 and a Dell B130 laptop. All computers work fine, but within the last week my internet has been on and off. If I'm on the web, I can continue through a site, but tryinig to change will kick me off. It might work for a half hour, maybe 2 hours, then out of nowhere, it doesn't work. It could be down for 5 minutes, maybe 3 hours. Internet connection problems are consistent among all three computers. The two desktops are hooked up to the router, laptop is wireless. Here is what I know and have done.
The modem always has a solid green light indicating consistent signal.If I unplug it and plug it back in, internet works again...usually for a short period of time (half hour). I have talked with ISP and performed their troubleshooting, which consisted primarily of double checking IE tools/options/connection/lan settings. On my laptop, the system tray shows continuous connection with excellent signal all the time. Technician from isp came and replaced modem with new one, same model, and by contact to isp checked all connections there and changed a couple of different setup configurations from their office (not on my computers). By his connection to the router, he had same problems on his laptop. I tried pinging gateway IP and it worked when the internet connection was on and off. Cannot ping any site by name (i.e. google.com) when connection is down, can when it is up. From inside the house, I tried pinging each computer from the others. HP to laptop was fine both ways. Neither pc could ping Gateway, nor receive from Gateway. "Request timed out" was the response.
I'm a beginner with technical troubleshooting, any suggestions or options would help. Thank you all so much!
