On my network some customers are facing problems with facebook where photos are not loading?

I had the same issue, and disabled “allow Remote requests” under ip - dns

That fixed it for me

Remote requests are enabled on my setup but having the same problem. Did you ever solve the issue?

to me sounds like mtu issues.
Packet sniffer will help us to diagnostic the issues

Did a small packet capture with wireshark, i do see some retransmissions and out-of-order messages there.

I already went over the MTU rates for the LHGG and the APs: Actual MTU is 1500 everywhere on all interfaces wifi + eth + lte. However on the LHGG the ether1 interface has L2 of 1600 and for lte it does not show at all and for every wifi interface (on the APs) the L2 is 1600 but the ethernet interfaces have a L2 MTU of 1598.

Any ideas?

This problem is not persistent it comes and goes.

I have also heard that on the LHGG the sim card pins are very loose and can cause some weird hickups in the network. However i have not seen anything in the logg for a while. It did go out at some point and point blank said that card is not inserted after a couple of tries inserting it back and cleaning it i managed to get it working. Also i have not seen any guides on how to fix the pins on LHGG. Maybe that can cause something as well, i have noticed that when looking at the lte interface the RSSI value comes and goes although the RSRP value itself is pretty stable around -52 dBm
