I'm finding that large (>200MB) transfers of data via the wifi network are extremely unreliable. They start out running at a reasonable speed (350KB/sec-600KB/sec), but within a few moments slow to less than 100KB/sec. The rates become very erratic, and the device GUI becomes very unresponsive.
Are you sure network is a problem? Are you writing data somewhere? Both MMC card and iternal flash are really slow when writing. I had similar problem when writing to MMC card. First it is fast because data is buffered in RAM but then RAM is filled and as you say 'GUI becomes very unresponsive'. You can use 'top' in osso-xterrm to see cpu usage. If it is mmcqd of something like that then it is MMC writing. Enabling multiblock writes helps (a bit experimental feature).
Only when multiblock writes in MMC driver are enabled then wi-fi driver really becomes a bottleneck. It theory it should be the fastest way how to get data into the device (g wlan does normally > 2MB/s speeds) but sadly only ~600kb/s is reality with N770 and current driver. I wonder where exactly the bottleneck wih wi-fi is (hardware of software).
