Hmmmmlet's hope it does not mess up your home wireless network.
With DD-WRT it was easy to do
I just set up my TP-Link MR-3420 as secondary router Connected to Beetel one of Airtel.
To keep it simple i used another SSID and didn't used it on repeater mode.
Any device connecting thru it is limited to 500kbps
I can always setup exception which i would do for my phone and Laptop.
Thank god No more doraemon on 720p on kids phones [emoji23] [emoji23] [emoji23]
