OK so when i am getting 4G (used to get it no problem last week) i am getting about 5-7 mb/s downloads.
i saw a thread over at XDA with other that have the same issue.
i have had bad 4G signal and speeds for the last 3 days on MR1, MR2 and MR2.5 radios, and various froyo/GB roms. even had my buddy in phoenix do it with the same slow results.
and i think this is NOT an LTE issue, i have a feeling it is a thunderbolt/LTE issue as my buddy who works right next to me has a Droid Charge and is getting great 4G signal with 60-20mb/s downloads.
i used to get 20mb/s downloads here at work, but the last few days it has been terrible.
