Wifi connection keeps dropping on PCI wireless card

My laptop has a Ralink RT5390 wireless card. As it currently stands, I can have about ~1-2 hours' worth of stable Internet before my connection drops and I have to plug in my USB adapter.

For the record, I just installed Arch on this laptop yesterday. It used to have Windows 7, but the situation on Windows 7 was identical in that my wireless connection kept dropping. I can't tell if it's actually the card itself that needs replacing or if it's just the fault of the Ralink driver. It was working just fine up until the beginning of May.

I made this account 10 years ago when I was an ignorant and insufferable teenager.
I apologise to all the people I annoyed with my cringe in the past.

Re: Wifi connection keeps dropping on PCI wireless card

I can't tell if it's actually the card itself that needs replacing or if it's just the fault of the Ralink driver.

It's not looking good from what little bit I can semi-decipher.

I drilled down on this part to find out what it means in human terms. I went to Linus's latest source tree because you neglected to mention which flavor/version of kernel you're running.

 3519.385470] rt2x00mmio_regbusy_read() Indirect register access failed: offset=0x0000101c, value=0xffffffff

From my amateur view, that's saying that the device driver was waiting for the BBP_CSR_CFG_BUSY mask bit (0x00020000) to go to zero in the BBP_CSR_CFG register (which is typically the Control/Status Register) on the adapter. It does this by reading that register 100 times with a 100 microsecond delay between each read. This is practically forever in computer terms. But after all those reads, the value that was returned was 0xffffffff. So the bit was still on, so the error message was produced and that function returned with an error.

I don't know why that's happening, but it doesn't sound good. While it's possible that it's firmware related, that firmware version is fairly old as it was added to the Linux kernel in the 2011 time frame and I assume it's still the latest level. I don't know if there's a kernel module parameter that might help because you also neglected to say which modules are in play here, but you can check that for yourself.

I also tried finding a datasheet for that RT5390 chip but Mediatek must be guarding it from us mere mortals. This thing appears that it might be a mini-PCIe adapter, so you might try reseating it if that's possible. But I wouldn't get my hopes up that will cure the problem anyway. Good luck.

Re: Wifi connection keeps dropping on PCI wireless card

How could I forget to put the kernel version? I feel like such an idiot sad I'm running kernel version 4.0.4, the latest one available in the core repository. As for what you just said... it's disheartening to say the least. I've had this laptop for damn near three years. I really hope the wireless card ain't dying on me now. If it helps, here's the output of lsmod (again, how could this have escaped my mind? I'm ashamed to call myself an Archer)
