Need help from the computer savvy folks please

[stevieray]

Hello,

I need wireless network help please.

I currently have a linksys wrt54g router and a linksys wre54g range expander.

The distance from the router to where I am trying to connect is about 125ft.(Outside back yard man cave/shed)
Router is in house by the rear door and range expander is in detached garage about 60ft from the router.

I constantly drop signal. Sometime rebooting cable modem,router,expander will help for a short time.

Are there any routers that will reach 125ft without an expander?
I have Comcast internet Performance plus or whatever. 16Mpbs

Any help or advice appreciated
