Have had DGL-4300 for almost 3 years, no issues to speak of. Not a networking guru, so router pretty much has all factory settings, only real config has been to set up internet filters on kid's machine. Just past few days, whenever one machine connects to the router via wireless connection, the entire router seems to hang. Can't bring up router admin page, can't access any Internet site, nothing on any machine (3 all told in home network) either via wired or wireless connection. Shut down the system using wireless, wait a bit, and plug into router and magically everything works (including connection allowing to make this post

. Not sure what might be happening, or what router config info might be useful but any help would be appreciated.
