Is it frequent internet disconnection issues?
If yes, then downgrade your internet speed one step down (i.e. 4mbps) and it will improve stability significantly.
PTCL lines are all old copper ones and messed up, that's why they cannot handle high speed broadband.
The others have limited bandwidth issues, so nothing is peace of mind. Lol
On a side note, don't seed torrents and change WiFi password. Lol.
I gave my wifi password to my neighbor (for basic tasks as his internet was having some issues, and the next day, 7 additional devices from his side were connected and internet ran like an overloaded donkey.
