I purchased the TP-LINK TL-MR3020 Portable 3G Router in Dec’12. I had never heard of TP-Link then and was only taking chances. Not many reviews on the internet then and the only word I had was my only friend who had bought TP-LINK TL-MR3420 (a bigger model with 3G capabilities). I was using a Tata Photon then and wanted to get it over WiFi.
Researched on its features and finally went for it. Ordered online via Flipkart, Priced then @ 1676 INR was a good deal. Easy to configure and awesome performance.
Due its size, it was natural for it to emit low signals after a distance but I have a 3BR flat and it was perfect to use. However the best part is its USB power adapter which means you can connect it directly to a laptop to save power.
I connected it in my car to the USB port and have a Mobile WiFi network ON THE GO! :)
TP-Link has captured a good market in India now and this product is still a good seller for TP-Link... Now priced @ 1517 INR.
