GL-X750 Upgrade from EC25-AF to EP06-A (or MC7455) worth it?

[Time-Pilot]

Currently using a GL-X750 with an EC25-AF and getting about 18Mbps max down with T-mobile.

Is it worth the upgrade to an EP06-A(or MC7455)? Would I potentially double my speed with CA?

Are there any recommended US vendors that have the EP06-A in stock?

I am also considering buying one of these KuWFI routers and tearing it it open just for the modem.

More info please.
What band you connected too? Signal strength? How far to tower? Using outdoor antenna?

Band 2 gives me the best connection and speeds where I am now. I can get band 66 but it seems to be less stable.

I get better speeds with a weboost vs without and even vs when I put the GL-X750 on the RV roof for a test.

I switched to the Taoglas TG.55.8113W internal antennas which seem a little better than the stock antenna

Current signal stats on Band 2
rsrp -84
rsrq -8
rssi -58
sinr 12

If I switch to Band 66 or Band 4 I get these but pings seems to increase & drop packets
B66
rsrp -89
rsrq -8
rssi -64
sinr 21

B4
rsrp -89
rsrq -6
rssi -65
sinr 21

I am in an RV though, so I am just wondering what kind of real world speed increases people get in general when upgrading to the EP06-A (assuming a good signal).

According to the signal strength you put up, your signal is great. Surprised not getting higher download speed than that.
Have you tried it in the off hours? Do you know how much Mhz you have on band 2?

Here is a generic formula. Say at my location using band 2 get get consistant download of 60 down on 15 MHz.
So 60 down / 15 MHz = 4 down per MHz. Now let's say it is now going to do carrier aggregation with band 2 and 12. And band 12 has 5Mhz on it.
So band 2 + 12 = 20 Mhz of band width.
Back to easy formula.
20 Mhz * 4 down per MHz = 80 down.

Now of course this isn't a perfect way to guess. It is the best way to try to do it that I know of.

Band 2 & 66 both say 10M down

Appreciate the calculations.

I'll get up early and do some more testing tomorrow morning.

Don't have to get up early can use this to set it up to run with out being awake. Set it up to run once an hour like 8 times or what ever. Give you like a chart with the results.

Also do think you can run band 2 & 66 with this modem. Certain modems do certain band combinations. Can look here for what it combines.
