WWAN Speed - MC7700
Hi all! I was able to get a Sierra MC7700 working with pfSense by setting the card to DirectIP mode. I got a data sim for it from Google Project Fi and am targeting LTE band 4 on it (t-mobile network).
It can connect, and I can even ping IPs when I route traffic through it, but it is abysmally slow. I'd assume only a few kbps. It's not fast enough to actually do a speed test from a site.
I've found that modems are pretty tricky and I don't know how to troubleshoot the speed of it. I know the following two AT commands contain important info:
Current Time: 505325 Temperature: 54
Bootup Time: 503988 Mode: ONLINE
System mode: LTE PS state: Attached
LTE band: B4 LTE bw: 20 MHz
LTE Rx chan: 2300 LTE Tx chan: 20300
EMM state: Registered Normal Service
EMM connection:RRC Connected
RSSI (dBm): -66 Tx Power: 0
RSRP (dBm): -96 TAC: 5600 (22016)
RSRQ (dB): -11 Cell ID: 00A3BE02 (10731010)
SINR (dB): 5.8
25 from CSQ is supposed to be pretty good signal strength, so I'm not sure what's going on. Hoping someone with experience in WWAN modems can point me in the right direction :)
