I've got a weird situation that I haven't been able to figure out. I've got a new Gateway laptop model MT6840 running Windows Vista Home Premium. This is the only computer in the home network and I've got a Comcast Motorola SBG900 wireless gateway. The issue that I'm having is connecting wirelessly when at home. If I'm at home and sit my laptop right next to the router I can see the wireless network and connect to it and then go anywhere in the house. If I turn on the laptop in another room in the house other than right next to the router then it doesn't see the wireless, as soon as I walk in the room where the router is sitting then it works and I can connect and then go back to the part in the house where I couldn't connect.
Here's what I've tried.
1. Changing wireless routers - same exact issue on a different router
2. Updating laptop and routers with latest updates/firmware.
3. Changing channels on wireless routers
4. Changing SSID's to non-standard names
There shouldn't be any interference from other devices, but even if there was, I'm not sure why this only occurs on the connection.
I'm thinking it might be something with Vista, since this machine replaced an old Windows XP machine that worked fine.
Any help would be greatly appreciated.
