Question
Cameleon 17
Hi everyone,
I have an odd issue since some recent network changes and it appears to be down to my HC2 - or something it communicates with or communicates with it.
So long time working setup I've had (UK based) is broadband internet from PlusNet (BT) and a BT Smart Hub 2 router
Broadband router <<eth>> Netgear GS108 switch <<eth>> [wired devices]
where [wired devices] are HC2, rPi/homebridge, Philips HUE, Windhager (pellet boiler), Heamiser (UF heating), Synology NAS.
Recently we've needed more speed as although we're on FTTC, we only get 15Mpbs download and 1Mbps upload. So we've moved to a LTE router in the Huawei B818. This thing flies compared to the BT connection, 130Mbps down and 30Mbps up. Initially for testing, as it is sited the other side of the house for the external antenna, I had it set up on an old Vodafone router as an AP (disabled DHCP and all that) and that only had internet access, all the other setup as above remained and had to access them on 2 different AP/networks.
Now I've tried to merge them but something isn't happy. Connecting the B818 to the GS108, we get some really weird behaviour. Internal LAN connections are all fine and super speedy. WAN based connection (i.e. the internet) are really unstable to the point that I have to refresh web pages multiple times to get them to load and sometimes they just dont load at all. Speedtest.net app sometimes connects fine and gets full 130/30Mpbs and othertimes fails completely, or download is fine but upload fails.
Through a process of elimination, I have worked out it is when the HC2 is on the 'new' network that the connection goes weird. But I have no idea why it would do this?! IP is set to manual, points to the new router properly and the internet light shows on it. Changing the IP or swapping to DHCP works for a while then it freaks out again. Again, all internal connections are fine, no issue getting to the management page on the device.
I dont have another dedicated switch to test with, but as a quick test I have hooked up my old BT SH2 and running the B818 to it and then onto the HC2, it appears to be working (as I type!). It only has 4 ports so I can only test another 2 devices on there with it, so can do some limited testing.
Any ideas? And how to go about nailing down the cause? Dodgy switch? Dodgy HC2?
