Which of these usb adapters should I buy (needs RTL8188SU chipset)?


Recommended Posts

...for a networked media box which requires an adapter with a realtek RTL8188SU chipset:

the options come down to a few omni directionals ranging from 6dbi to 2dbi and a 10dbi panel antenna.

i have a single story house and the signal needs to reach about 50-70 feet away, so the higher dbi omnis ought to be more optimal (right?).

You can do dlink if you want zero customer service or support...and forget about any chance of legitimate rma in the event of a failure...cisco/linksys is probably best, netgear and buffalo would be my second best, then the others...

Its safe say they will never get another dime of my money...you guys are top notch techies fully educated to make informed decisions, maybe my unfortunate experience was unique, but I don't think so...btw if you do have problems with them it helps to be fluent in Hindi...
