Just restarting the router helps? also check the Bit Rate, and Link Quality.

Code: Select all

Couple of things:

1. You might try an antenna switch:

Code: Select all

sudo modprobe -r rtl8723be && sleep 5 && sudo modprobe rtl8723be ant_sel=2
If that is better:

Code: Select all

echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be.conf
2. Disable power management for your WiFi chipset:

3. If that doesn't help, try a supported kernel instead of your current (UKUU?) kernel....

4. And for that supported kernel, you can try a driver switch:

Do you have neighbors close by? One typical cause of Wifi slow down is having neighbors using the same frequency channel as your router. If you are on 2.4 Ghz, it's more prone to this type of interference compared to 5 Ghz.

I use Wifi Analyzer on my phone to check for neighboring routers which maybe using the same frequency channel as my mine.

Have you recently installed any household appliances which maybe on the same frequency as your wireless router?
