I don't see why the laptop aerial would be under suspicion. You wrote "Wicd worked for a few days", and the aerial is unlikely to cause that sort of variability. But I think your paragraph above is the first (indirect) confirmation that the phone is connecting via WiFi when you conduct your tests, and aerial technology may make a difference, as might using a WiFi dongle with a decent aerial attached. (That does prejudice its portability, of course.) We also don't know the favourability of location for the two devices, and with wavelengths well under a metre, small distances can be significant. Other traffic on the same channels is another factor; though I am wondering why you're vague on 2/5GHz. Surely you know whether you're using 5GHz just by checking the sessions in the device, or even the access point (depending on how you configured it). All that said, the speed measured on your laptop is so low that I can't help suspecting you have something set up wrongly, or some unfavourable circumstance. My 17-year old laptop can transfer at around 18Mbps through its 2GHz WiFi. Now I'm measuring under favourable circumstances: the router is on the floor of the room above, and the source of the bits is scp from a local wired machine. Obviously it would help with troubleshooting this problem to eliminate (or separate) the factors involved, eg: . browser use wget to download a large file from a "good" site . internet copy a large file across just your LAN . laptop disk copy a large file across just your LAN to /dev/null .
