Hi guys,I have been using this modem since past week, and it's working fine for my airtel 3G. The usual speeds I used to get from my locked airtel dongle was around 4-5 MBPS, and with this I am getting 2.5-4MPBS. So, comparitively it is slightly lower, but still it's ok for me as I can share my connection now very handily, which was not possible with the airtel dongle.The problem I am facing now is that I inserted my micro SD Card in the modem yesterday. Since then, I have not been able to surf at all! The modem connects to the internet, but just does not give any speed back to the devices. As soon as I remove the SD Card, it starts working like charm, again! I have tried everything- restarting the modem, resetting the modem (factory reset), using it through USB, using it through wi-fi, but it just doesnt work. The files in the SD card can be easily accessed, but I just can't open any webpage, or work on internet. Is anyone having a similar issue? Any idea why this is happening? Any help will be highly appreciated!Thanks n regards,Ragz
