WIFI Signal goes less than 10'

[BrewGuyFromHP]

Laptop will drop signal before leaving the room. Same for my DROID RAZR.

Using DSL with a Westell 327W router and Windows Vista. Router and Toshiba Laptop are in the same 1st floor office.

Router is located on top shelf of computer desk adjacent to an inside (not outside) wall.

Cordless phone is in office but nothing changes when phone is unplugged

Signal strength goes between "good" and "fair".

Have tried changing Channels (11 does better than 1 or 6).

Does it make sense that (1) there is a router issue; (2) a poor DSL signal or (3) something else.

Thanks...
