Hello,
I have just installed new cable modem/router(Motorola)
Mac,PC Laptop,I.pad and I phone are working great, my HP desktop with build in wireless is having major problems.
Very weak to no signal detected, when I take laptop to same location it has no problems at all
Wireless connections are dependent on a lot of things. What kind of wireless adapter are you using with your desktop? Is there an external antenna for the wireless adapter?
