Cost of USB to Ethernet port will be about Rs 500. I bought it for same cost. I found some of the ebay sellers were selling for Rs.250 as well. I tried other online selling sites like Flipkart and Naaptol but this component is not available. I don't know how to choose good port and So I choose Rs.500 port.
How to connect
Below I have given steps to connect USB to Ethernet port in Android Tablet.
Step 1: Connect a USB side of USB to Ethernet port to tablet. If your tablet doesn't have USB then you need to purchase mini-USB to USB port.
Step 2: You will find a wire connected to your router as LAN (mostly in Yellow or Blue color). This LAN wire has two ends. One end will be in your router and the other in your PC. Plug out the LAN connected to your PC and Plug in the USB to Ethernet port.
Step 3: You can find light glowing inside USB to ethernet port. Also, there will notification in your Android tablet.
Step 4: Then open your "Default Browser (pre installed in your tablet)".
Step 5: Your tablet is now connected to internet via ethernet port.
Can we access internet via USB to ethernet port in Mobile
Yes, if you have ethernet option in your mobile settings then you can access internet via USB to ethernet port. I haven't tried in mobile phones. Just go to your mobile settings and search Network settings. If there is option like "ethernet" you can access.
Only advantage is the investment is less and you can make use of your router / modem wisely. If you want to purchase a Wi-Fi enabled modem it will cost you Rs.1500 which is the minimum price. If you are the only person going to use internet, then choose this port. If there are more than one person and want to access internet in several device choose Wi-Fi modem.
