TPLINK MR600 wifi not connecting to any android device except pc
I'm using tplink mr600 from last 5 month with India VI (VODAFONE-IDEA) SIM and had no issues but from last 2 days I have started facing some weird issue about internet. I can access and use internet on my laptop through TPLINK mr600 by WIFI/Ethernet cable but when I try to connect MR600 Wifi to any of my andriod devices it says no internet on android. It was working fine before but I'm facing problem from last two days.
I have inserted sim in two of my android devices and the internet work fine there but problem persist in tplink mr600. I have updated to latest firmware 2 3 times from last two days, tried everything but no luck.
I'm attaching few image!
