To speed up your Sprint hotspot, try this:
Go to http://myhotspot/index.html#setting
Sign in (the password is passwoed)
Basic
Change
Authentication Method
WPA2-PSK
Encryption Method
AES
Also change:
Advanced
802.11 mode to G or N (G works best for me)
WiFi channel to channel 6
This pretty much doubled my speed.
I was waiting for one guinea pig to try Calyx.
I figure the worst is they lose their contract, like Jeddak dispute charges-get money back and keep hot spot then look for another provider until the market allows other options.
It sucks but at least it's an option for $50/month of reasonable internet access.
I really appreciate you posting up the information above and when my stuff (ordered the $600 package) arrives I will try this to see if my speeds improve.
