ath: phy82: Failed to wakeup in 500us #72

Open yipperr opened 9 years ago

hello i am using a alpha awus036nha in ubuntu with 3.18 kernel causes a lot of disconnects where the whole driver reloads itself and the usb layer is deinitialized

here is the dmesg

added notes tried on usb 2.0 and 3.0 ports its not the usb layer but the driver itself just so to rule out hardware the alpha nha works solid in windows while connecting to wifis

I just opened my tpe-n150usb adapter from ThinkPenguin; it was a bit difficult to open: I used a small flat screwdriver to push the black plastic pin on the metal sleeve then pried around to push back the black plastic casing.

Here are some shots of the board; I trust the bigger '13 NCJI C3101075X01' identified chip is the AR9271, and I also identified an STMicroelectronics 24C08RP EEPROM (8/16KB) and a BDC 9706A DC/DC voltage converter (https://www.diodes.com/assets/Datasheets/products_inactive_data/AUR9706.pdf).

Perhaps I should probe with a DMM around the converter to verify the voltages are expected.

yes, try on those two big flat SMDs. before that, have you tried connecting the device through a 1m extension cable, or you plug it in directly into PC ? try cable if you have one around just to see if anything other happens in log

Hm, I've tried connecting it, but it's difficult while its case is disassembled: I shimmed it into the USB port using some thin polystyrene foam sheet. It appears completely dead (dmesg is silent), whether I connect it directly (the usual case) or via a 1 m USB extension cord. I hope I haven't made it worse :-).

I'm lacking lab instruments here to do the measurements, unless I can somehow use my computer as both a function generator and an oscilloscope to use one of the tricks explained here: https://www.wikihow.com/Measure-Inductance (I think I've done so in the past for the scope part, using xoscope). audmes looks like another option for the oscilloscope part.

@psyborg55 I'm not well equipped/motivated enough to fix mine. If you are interested, I could ship this to you free of charge; otherwise it'll soon find its way to the dust bin.
