Hello
My neighbour and myself had very much different download speeds, me using a Chatau LTE12 and himself using some other brand mobile router. As an experiment I brought my Chateu to him, tested on his ext. antennas mounted on the roof and suddenly the download speeds were much better, same as for me. The antennas are placed correctly by a contractor who does rooftop installations for companies and homes. The RSSI/RSRP/SINR/RSRQ confirm that, values are pretty similar for both of our devices.
Encouraged by these results he bought a Chateau for himself, we've put in his SIM, connected to his antennas and the results were pretty much the same as on his old router... The difference is not neglegible - when I get 30Mbps he's getting 3Mbps. External antennas are enabled in his configuration and I've confirmed on my router that they are working ok.
I'm running v7.1beta5 and he could only upgrade to v7.1beta6 so other than having a physically different SIM card there are not much differences between our setups.
Is there anything about v7.1beta6 which could affect the performance so badly? I'm really afraid to upgrade mine to it to have severely limited internet access and on the other hand I haven't found a way to downgrade his router to v7.1beta5.
Is there anything which could be tested further? I don't really undestand why the same device with pretty much same config works so badly.
