I want to sell off my old TP-Link TL-MR3420 3.5/3.75G Wireless N
Router that I've purchased from Challenger about half a year ago
for $35.
It has already been upgraded to the latest firmware and is rarely
used since I've switched to Fibre. You can insert
your SingTel/M1/StarHub
3G Mobile Modem into the USB slot and use the modem to
share the connection via Wi-Fi or LAN! The router is extremely
configurable via its web-based interface. If interested, please
contact me at 96157836
