For 3rd party uses of the R11e-LTE, could you at least provide the AT commands disabling the unsolicited status/progress messages?
These may be interfering with chatscript. e.g. after a AT+CFUN=1 the modem puts out a lot of responses, including some of them after the "OK" response.

Re: 1 Gbit/s connection, need router upgrade?

FYI: I just upgraded my RB1100AHx2 to a CCR1009-7G-1C-1S+ on a 1000/500 connection (dual wan, a lot of filters, 300+ tunnels, thousands of routes, NAT, no fasttrack...). The 1100 did some 900Mbps at 70% top processor load, while the 1009 gets 925Mbps at 7% load tops. So I would say both can do the j...

Re: RB260GS Stock

Take a look at the hEX PoE (since there is no hEX with SFP without PoE):

Re: PtMP VLAN ISSUE

For this issue I need to understand if there is a way to build two segregated wireless interfaces in the above mentioned hardware or if there is a way to improve the bandwhith given that the main equipment can handle almost 1Gbps.

Re: Can i Route Like this?

You could use vlans for this if those are managed switches supporting vlans: Connect your ISP1 as untagged to a port on the first switch and use the fiberlink as a trunk. On the second switch do the reverse. But since your RB750 is already connected, you could use the same physical interface to tran...

Re: Mikrotik Experts you are in need!

Put a sniffer on your network (or even use torch with all checkboxes enabled) and see for yourself.
