WiFi is for all intent too easy to see issues with since it can drop due to simple things like an old 2.4GHz cordless phone.
I didn't see where you tried a direct connection.
Hi - I have tried to find a reason for this and have been unsuccessful. At the start of the Olympics, my wife was watching it via the internet and all of a sudden the connection disappeared. At the same time my desktop was no longer connected. After about 10 minutes it was OK and I thought it was just a provider issue. It happened again later on and continued to happen over the course of the week. The other day I noticed the same thing when browsing videos, a number of them in a short period of time. A disconnect, and then back in about 10 minutes. I contacted the provider and was told it was probably a network problem at my end as they showed no interruption to service from their end. I told them that during this "outage" I could clearly access the pc's on the network. I asked if modems buffer as I thought maybe too much info was coming through the system and was creating a log jam so to speak, and was told modems do not buffer. Today I experienced the same thing but this time it was not video, but rather about 25 searches on ebay in a period of about 4-5 minutes. As always, came back in about 10 minutes. This happens on different pc's both running XPSP3, and using different browsers, one Chrome and one Opera. All I can think of is that I don't have the most up to date version of Flash (though its not that old) or maybe the modem has gone bad, though I read that that does not usually happen. I am pretty sure I can easily recreate the hang, but if the provider isn't seeing it in their log I don't know how much help they will be. If it helps, the router is about a year old, a Linksys wireless G, 2.4ghz and the modem is a Best Data, which is at least 3 years old. Any ideas you might have will be greatly appreciated.
