How can I get my usb wi-fi adapter 25 ft. away from my computer with little (or, not too much) SIGNAL LOSS?? Answered

I can connect my usb device with as much as 15 feet of cable. When I add another 10 foot cable on to that, it won't work (sometimes it will, but just for a few minutes before turning off). I've tried adding a self powered usb hub in between, but no luck..it's a 2.0 hub, but pc tells me i'm plugging into a low speed port? I am willing to cut, splice, solder, or blow torch!! Anything that will work! 


Are you connecting to the computer and usb wifi using usb2.0 cables?

Yes. Even when I use a short 2.0 cable to go from the computer to the hub, and then plug the adapter into the hub itself, I've got the same problem.

Hmm...that sounds like your USB hub isn't functioning properly, or you're not plugged into a USB port at the computer itself.

For instance, I have SUB 2 functionality at the motherboard level, but the schlocks who assembled the PC subbed a USB1 output 2-port to the front of the computer...So even though that 2-port is plugged into a USB 2 host, it is the bottle neck for anything I connect to the front port, and so I have to connect to the back for any USB2.0 devices to get full speed access.

If that's not the issue, then I suspect your USB hub is the problem.. Have you confirmed it's operation using the 15 foot cable and another USB 2 device?

I have. I connected my mp3 player to the hub (connected to the pc via the 15 ft. cable) and I do get connectivity, but  XP notifies me that I am connected to a non-hi speed port. I tried the back ports after reading your msg., but no luck. I downloaded some trial software that tells you the status/speed of all the pc ports.....The hub is recognized as a 2.0 "generic usb hub", but the speed of the ports on it were listed as "full speed", and not "high speed". The documentation on the hub says it is capable of up to 480 Mps, so I'm just totally confused at this point. I was thinking driver, maybe? But I can't find any other than the Intel standard. I guess when I get the chance, I'll try someone else's hub in the same setup and see what happens. I appreciate your reply VERY MUCH, thnx.

The hub is recognized as a 2.0 "generic usb hub", but the speed of the ports on it were listed as "full speed", and not "high speed".

One or more of the following is true.
a) the usb chipset on the motherboard is not usb2 compliant
b) the physical port on the machine is not usb2 compliant
c) the USB A//B cable connecting the PC to the hub is faulty or not usb2 compliant
d) the hub is not compliant or not usb2 compliant when loaded..
e) the device under test is not usb2 compliant

note...with the exception of "c", append "or is faulty" to each of the above statements

Thank you. After eliminating what I could, it comes down to c or d. Appreciate your help.

You're welcome. I'm glad you're getting closer to a solution

One thing more of note...I've always heard that "self-powered" USB hubs are more likely to fail USB2 connectivity. My guess is that it's because of their own use of power derived from the USB connection upstream (at the PC), so if you have one to test with, you might want to try using a powered USB hub to check at least item C

Jut try a search on google or your favorite search engine for " self-powered USB2 hub failure" or "self-powered USB2 hub problem" to see what I mean...

 usb by spec is limited to 16 feet.

i can think of two things:

1) use a usb over ethernet extender.

2) splice the usb cable so that the power lines run from a wall supply to the usb wifi adapter, and the data runs to the computer. (this is not the optimal solution)

I have thought about the usb over ethernet..the ones that I looked at only supported usb 1.0, although I haven't looked at too many yet...Maybe I'll give the power line splice a try...Thanks for the reply!
