I upgraded a Lenovo newifi mini wireless router (WikiDev) to 17.01.2 recently. However, I found the download speed on 2.4GHz WLAN is less than 100KB/s. And
dmesg output contains a lot of errors
ieee80211 phy1: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2
Has anyone encountered such problems?
