Region : India

Model : TL-MR3220

Hardware Version : V1

Firmware Version : 3.12.11 Build 120320 Rel.42138n

ISP : Vodafone

Just bought this 3g router after finding the Vodafone 3g dongle (ZTE K3770 z) listed as compatible.

Just can't get it to work. It connects to HSPA mode and then disconnects immediately and goes back to identifying process and the whole cycle.

I tried latest firmware and India call center of Tp-link sent current one by email. After 4 calls, various settings, remote help through my laptop (where the dongle works fine) the call centre told me that all tp-link 3g routers work only with dongle that do not use SIM. This is strange because Vodafone told me that this model does not come without SIM.

Any help on this? Any one with any experience?

Thank you...
