Hi guys,has anyone succeeded on this? As opposed to other routers from Linksys, Netgear, etc., the antenna itself cannot be unscrewed (there's a small plastic stub). Then again, it's a regular antenna; don't see why it should be any different from any other.The connection is very week in the master bedroom. I am tempted to clip off the stub and if I can screw off the antenna and have it replaced with an aftermarket 6dBi or so version (these are dirt cheap if bought from eBay sellers in Hong Kong). Anyway, would appreciate if anyone can share his/her experiences upgrading this model's antenna or can comment.Micho.
