Poor transfer rate in Sierra MC8755

[miszka]

Hello,

I recently bought an IBM X60 with built in gsm antenna and modem as above.

I've tried to check everything from hardware side, but no effect. I have week range (comparing to my huawei e160) and transfer (e160 gives me about 100kb/s and sierra max 40kb/s).

Both modems are connected in the same place and in the same network (the same sim card).

I have upgraded firmware to 2_45MCAP version, but with no improve.

Any help?

Thanks,
M.

I was never able to get any better than plain 3G (384kbit/sec) out of the MC8755 card that my X60s was shipped with, even with the latest firmware.

I ended up upgrading my X60's WWAN card with an MC8775, using a Zender BIOS to allow it to work.

I have the same problem. Though! When using Elisa(Finnish operator), the card Downloads 1Mbps and Uploads 0.40Mbps. BUT when on Sonera(another Finnish operator) the download speed is closer to 0.40Mbps on XP and 2kt/s on W7. The card was unlocked. However, Elisa's card's seemed to work on the Vodafone card before it was unlocked

Just can't understand.

I had exactly the same issue with my MC8755, just 384Kbps connection. I got a Lenovo branded F3507g, taped pin 20 and installed a Zender BIOS. It connects at a theoretical 7.2Mbps, but the max download I've seen is about 3Mbps. Works beautifully though.
