I have a Broadcom BCM43142 chip, it works normally as of Debian 9. But after upgrading to Debian 10, it displays this weird behavior of automatically disconnecting from WiFi, reconnecting successfully for 3 seconds, disconnecting and the cycle keeps continuing. It has lead to websites loading really slow or failed to load at all. Here is a snippet of sudo dmesg :



[ 1073.310482] IPv6: ADDRCONF(NETDEV_CHANGE): wlp6s0: link becomes ready
[ 1107.065818] IPv6: ADDRCONF(NETDEV_UP): wlp6s0: link is not ready
[ 1107.065852] IPv6: ADDRCONF(NETDEV_CHANGE): wlp6s0: link becomes ready
[ 1145.315969] IPv6: ADDRCONF(NETDEV_UP): wlp6s0: link is not ready
[ 1145.316005] IPv6: ADDRCONF(NETDEV_CHANGE): wlp6s0: link becomes ready


And here is what happens when I run iwconfig twice:



$ sudo iwconfig
enp7s0 no wireless extensions.

wlp6s0 IEEE 802.11 ESSID:"TP-LINK_754E"
Mode:Managed Frequency:2.457 GHz
Bit Rate=58.5 Mb/s Tx-Power=200 dBm
Retry short limit:7 RTS thr:off Fragment thr:off

lo no wireless extensions.

$ sudo iwconfig
enp7s0 no wireless extensions.

wlp6s0 IEEE 802.11 ESSID:off/any

Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off

enp0s20u1 no wireless extensions.

lo no wireless extensions.


It can be seen that wlp6s0 was connected to my wifi then suddenly dropped off for no obvious reasons.



The problem is not because of the router or the chip because I dual boot with Windows and it works normally. Do you guys have any suggestions?
