(SOLVED)Mint Cinammon 14 / Sony Vaio / Unbearably Slow Wifi

Postby torren on Wed Mar 20, 2013 8:47 am

The Laptop is a Sony Vaio VPCEE23FX.

The Wireless Card is an Atheros AR9285, I have installed the window 7 drivers for this card via ndiswrapper and can connect to networks, even load pages. Simple pages like Google (load fine) something like Facebook not so much and you can almost forget running Updates. Before anyone makes mention: this is not a router/home net problem -- all other mobile devices use my wireless just fine (even this laptop did using Windows 7/Ubuntu) I REALLY like mint and don't want to be forced off of it by "slow wifi"

* V. querying DHCP...
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd

I have already done tricks like increasing wireless card to 54MPBS and adding "options ath9k nohwcrypt=1" to ath9k.conf in /etc/modprobe.d/ while these improved the insanely slow connection after installing the driver, they still have not brought the speed to nromal. I humbly ask assistance so that I may keep using this wonderful distro instead of being forced back to "user-friendly" Ubuntu.

p.s. Not sure this will be any help, last night I installed WICD in an effort to speed up the wifi connection (as was mentioned in some threads) and just a moment ago I brought up the WICD connection info:

I sat watching it as I attempted to load different pages and the speed fluctuates a lot, sometimes @ 13mpbs, sometimes @ 39mbps, sometimes @ 54mpbs and I even seen it register a 60+mbps
Thanks,
Torren
