I also noticed that if I put the 3.5 on SM the signal drops me 5dbi, how come this happens?

I just bought 3 ePMP 1000's. They all have 2.6.2-RC250 installed. I have attempted to download 3.5 GPS Sync as well as the full package and neither firmware will download. I get two intilizing firmware messages. One in blue and the other in red. Can anyone help?

I attempted the tar-gz firmware as well as the pkg3 firmware. Neither worked.

I think there was a step process, but can't remember for sure what it was. try going to 3.2.1 first.

Has the 5dbi signal drop issue been addressed in the past? It looks like it occurs when going from 3.2.2 to 3.4 or 3.2.2 to 3.5.

Hi Brad,
There were several fixes related to RSSI calculation accuracy introduced in 3.x firmware.
Could you please check whether SNR wasn't changed?
Thank you.

RSSI is what changed but it doesn't look like SNR change so I think everything is good.

Brad, thank you for checking.
So, difference in RSSI is caused by fixes to make it more accurate.
It doesn't affect throughput or any other link performance parameter.
Thank you.
