Solution Manual Band Selection for 4G Wi-Fi Routers and LTE Gateways
If you have experienced an issue of disconnecting or slowness on the 4G Wi-Fi router’s network due to the auto band selection, Please download and install the following beta firmware on the router to manually fix the band.
Please be sure you have read The Beta Test Agreement before proceeding!

Note: For MR600 v1/v2, Please note that not all combinations of the 4G bands are supported in 4G+ mode. Only when the router and the SIM card support the same combinations of 4G band in 4G+ mode, the bands might be aggregated successfully.
Besides the beta firmware, it is also planned to release the official firmware for Band selection. Keep an eye on the official website or router web GUI for the new updates.
If you are not sure about how to select the band manually on the router web interface, check the instructions below:

Thanks for your detailed testing. Actually the engineers should perform lots of tests before releasing a new official firmware, so no worries about that. While we do appreciate your guide and suggestions for others, which may help a lot.

I have commented here my positive experience about MR6400.
Unfortunately I have to change my "review". It's probably not about the new beta firmware but I have recently faced serious issues in the local network in which one ISP of two is this modem, providing internet in a condo for dozens of flats and even more devices connected.
It seems that MR6400 can't handle more than a couple of devices loading webpages simultaneously. I would like to know how many sessions it can handle because it just happened that even if the bandwidth would be suficient, the webpages couldn't be loaded when higher number than one or two devices try to go to the internet.
I remember when I unboxed the product and started to test it, still without the planned environment, just connecting two computers to separate LAN ports and started speedtest simultanously, the ping time shown in the test jumped up to hundreds if not thousands of milliseconds!
Is it the weakness of the device?
Is MR100 stronger? Is MR600 stronger? Could any of these handle dozens of connected devices?
Oh, one important detail: the wifi has remained off, I didn't want to weaken the performance with it. And when integrated in the local network, there was only one LAN port used, connecting the MR6400 into the R605's WAN port.
I tried dynamic and static IP. I tried limiting sessions into whatever low possible (even 80) per device.
I tried bandwidth control. I even lowered the bandwitdh parametres radically in the R605, regarding to the MR6400. E. g.: while the real bandwidth would be around 50 down, 25 up, I tried setting just 1Mbit or even less, so the R605 would direct most demand to the other WAN port with stronger microwave net. Nothing has worked.
I'm sad. I really liked this modem but this way it's not usable, perhaps in the winter when just a couple of users are in the condo.
Why doesn't TP-Link advertise it as a home router with very limited hardware capacity to only one or two devices?
Sorry for the bad review.

Hi @Arion
Why doesn't TP-Link advertise it as a home router with very limited hardware capacity to only one or two devices?
This could NOT be the design or advertisement, let me know if you find this advertisement in the official website.
We will try to make the issue clearer, you have the MR6400 connected to the ER605 VPN router, am I right? While I guess that is correct that the MR6400 is designed to be a home router, it may be not suitable for a business environment if you want to connect lots of devices in the network.
You can do a simple test by connecting the client devices directly to the MR6400 either with LAN or wireless, to confirm if you can access the internet properly. If yes, I guess you will need to review the settings on the ER605 for some basic settings, you may try to reset it to factory defaults first, connect it to the LAN of the MR6400, then check if the internet will work automatically, check if you can access internet on the devices that connected to the ER605.

Thanks for the reply.
I don't want to go off-topic here, so just briefly:
MR6400 works if I connect one device or if I connect even more devices via R605. It just can't handle more than a few. (how many exactly, I don't know.) I tested with the latest official and the beta firmware, as well. No difference.
As I said above, I tried configuring the R605 with bandwidth control, session limit (even to as low as 80). I tried defining the bandwidth of the 4G modem to a very low value to lower the demand from the R605. I checked the Session list, there wasn't any devices surpassing 150. Still it made the network unstable. And in the problematic time, 4G signal was at 75% and speedtest (connecting a single device only) showed up to 50Mbps download and 20-25MB upload. In the same time, the other ISP (microwave) with 80M/10M alone handles the demand just fine, at least so far.
If MR6400 is not suitable for business environment, which 4G modem of TP-Link product line is? Is the MR600 more capable for higher demand?
I didn't use the wifi or VPN in this configuration.
And as I also said, connecting only two PCs via the LAN ports of MR6400 and starting speedtest simultaneously made the modem struggle to handle it, producing ultrahigh (500-1000 times the normal) ping. That makes me suspect something.
I kind of regret I didn't choose MR600 (or Huawei B818) instead but nobody has published a comparison test on the internet about which of these can handle what amount of demand.
