Hi

I got this Argon iNet1, which has troubled me some. The unit wont find any wireless connections when scanning, but ethernet works like a charm. Tried running the router in b/g mode only and without any security, but still no luck. After that I pretty much gave up, and came to terms with using the ethernet cable. Now a couple of years later I'm getting really annoid with the dangling cable, so I tried pulling the radio apart and found that the wifi adapter (Ralink rt2571wf) doesn't find any networks when plugged into my PC either. I guess this points in the direction of a malfunctioning adapter. So an easy repair would be to get another verified adapter, only thing is that they seem to be rather rare to come by, especially if you want it to be cheap. I then stumpled upon this Belkin f5d7050 which uses the same rt2571wf internals, but hasn't been verified as a functioning replacement, though these lists aren't exhaustive of course. I really don't want to throw a lot money at this, as the radio itself represent very little value, but this specific adapter can be had so cheap, that I can justify the buy if the probability of succes is imminent  :)
So should I expect that any rt2571wf adapter will do the job, or is it a complete shot in the dark?

I can't give you a 100% guarantee but any 2571 based dongle should work.

However, you need to be aware that, particularly with USB Wi-Fi dongles, some manufacturers have used different chips in dongles with the same model number.  There are 5 different versions of the F5D7050 shown on the Belkin support pages and there is a different driver package for each of them, so I would be concerned that only one version used the 2571 chip.  I have downloaded all 5 and had a look through the files they contain.

V1  Prism chipset?
V2  VID_148F&PID_2570
V3  VID_050D&PID_705A
V4  ?
V5  VID_050D&PID_705E&REV_0200

VID 148F PID 2570 has RT2570 (usb-ids.gowdy.us/read/UD/148f)
VID 050D PID 705A has Ralink RT2571W (usb-ids.gowdy.us/read/UD/050d)
VID 050D PID 705E has Realtek RTL8187B (usb-ids.gowdy.us/read/UD/050d)

I've looked at the Sharpfin info page on two of my radios (different makes) and both have "Vendor:Product = 148f:2573".  However they are using the RT73 driver*.  That driver supports the devices listed at http://cateee.net/lkddb/web-lkddb/RT73USB.html.  The 2571 and 2573 are on that list.  Also the Belkin F5D7050 v1 and v2 using Intersil (=Prism) chipset.

My conclusions are that only a F5D7050 v3 (FCC ID K7SF5D7050B) is a 2571 and the v5 certainly will NOT be suitable. V1 and v2, maybe.  V4, cannot say.

* The firmware contains only two drivers - rt73 and a driver for Zydas chips.  The latter driver or the Zydas chips are intolerant of 802.11n signals (even if they are only neighbours to a wanted 802.11b/g one) so best avoided.

Hi Drgeoff

Thanks for your answer, it's very appreciated  :)

I'm aware of the fact, that most adapter may have their chipsets changed in later versions, which makes sourcing a worthy replacement even harder  :(
But this particular Belkin I have seen the naked inside of, and it says rt2571wf on the chip, so I guess it should be a rather safe bet  :)
