MT7921 wifi tx urb failed #6500
Comments
What else is attached to your 3B+? The linked thread is very long - please give a link to the bit that makes you think that the two issues are connected. |
Spontaneous transaction errors followed by disconnect/reconnect are usually a symptom of the device exceeding the available downstream port power. What happens when you plug the dongle into a powered USB hub? |
After the discussion in #6460, I connected an external power source to my USB WiFi adapter, and since then, there have been no power supply issues.However, after switching to a new USB WiFi adapter, another issue gone on. This time, it should be a kernel-related problem. Additionally, according to morrownr/USB-WiFi#410, this problem also affects x86 devices. |
also see morrownr/USB-WiFi#477 |
ok, it is a issue of bad usb cable |
Nobody should be surprised - we've seen many shockingly bad USB cables over the years. |
No,It not a usbcabel issue.This problem has appear again.I feel like it's related to the signal strength |
But when this error occurs and the network is disconnected, there is still a link rate of 300mbps. |
