Yes it will work fine. Just remember to keep them on different subnet, eg.- UTStarcom on 192.168.0.x and tplink on 192.168.1.x because if in case both of them are on 192.168.1.x it will cause dhcp conflict.
Hi @Mohammad bhai. I contacted airtel and they gave me the lowest plan for 2mbps@699 till 5GB and 512kbps post FUP. Will migrate to it soon. Cheers.
