| |
Hi,
I have a Sierra Wireless MC8780 UMTS card in a Fujitsu S6410 laptop running kernel 2.6.28.7. In kernel sierra driver v1.3.2.
The card works but speed seems limited to approx 1.0 Mbit/s download using the linux driver. Testing the card in Windows XP yields download speeds close to 5.0 Mbit/s.
I recently updated the firmware of the card to support HSDPA/HSUPA. The update gave the desired result in Windows but not in Linux. The speed improved in Linux but didn't increase above 1 Mbit/s.
Is there any known driver limitations or is this a configuration issue?
Please let me know if you need any additional information.
Best regards, Ralf
