Your settings. Have you set it up per our note at http://forums.cnet.com/5208-7589_102-0.html?forumID=62&threadID=264135&messageID=2584349 ?
Currently I use a D-Link Limited Edition Extreme N Gigabyte router (and have been for the last month or so) with no problems what-so-ever until last night I began having strange connection issues.
Every few minutes (actually it could range from a minute or less anywhere up to 5 or 10 minutes) my connection would drop (typically only for a few seconds but ranging upwards of a minute or two at times). I used the online virus scan Trend Micro "HouseCall" and it did not detect any trojans / malware / grayware. The problem persisted (although there were no issues noticed until evening time) through today up to the point I am posting this.
I am now running ZoneAlarm in an attempt to combat this (on the assumption it may be an outside source effecting my connection) and have had 2 incoming attempts to access my computer from 2 similar IP addresses (all digits were the same except for the final set). My reason for assuming that this is likely being caused by an outside source is because no one else in the house has been having the same issues and the router / modem itself does not appear to be losing connection with the internet.
If anyone knows what may be causing this, or ways that I can fix the issue it would be most appreciated.
