Hub 3 (in modem mode) is connected to an newly purchased unmanaged switch (TP link). The switch is connected to an ASUS wireless router (situated elsewhere on the house) and a Virgin V6 box. The switch effectively replaces an older ASUS wireless router which has now been removed (was working fine in this configuration).
If I power down, connect one device (via the switch) and power up, all is well. If both devices are connected only one will work. If I get one working and try to connect the other, the device connected last will not work.
Cables ruled out by connecting one at a time (or directly to the hub).
Any ideas? Do I need a managed switch or a wired router here?
1. Do as the other guys suggest and put the switch behind the router.
2. Leave your devices connected as they are but put the hub back into router mode and you'll need to configure the ASUS as a wireless access point. The benefit of this is that you'll have both the hub and the ASUS providing WiFi. And you may not even need the switch as it depends on how many devices you need to connect, if it's just one or two then omit the switch and connect to the Asus.
Thanks for all the input. Option 2 looks most flexible. I thought I’d read somewhere that the Hub router was somehow less capable than one from ASUS/TP link etc. but if it will do the job (reliably), I’ll go with that!
Out of interest, why do people switch to modem mode in this sort of configuration. Is this just to disable wireless operation?
Modem mode is for when you want to use your own router for broadband and WiFi, partly because the hub is notoriously bad for configuring.
To set up your Asus: log into it, set its IP address to the same IP segment as your hub's (something like 192.168.0.8) and disable its DHCP server. Initially I'd have the Asus's SSIDs to be different to those of the hub's. With only the Asus connected by any of its LAN ports to the hub, reboot the Asus and you should get broadband and WiFi.
So, have had a play around with the ASUS configuration and it appears option 2 (disabling the DHCP server and reverting the Hub to router mode) might be a no go. The ASUS is actually the primary router in an AiMesh network and it appears that the DHCP server may be required for configuring the node.
Assuming that I can’t leave DHCP enabled on both the Hub and the primary ASUS router, seems my only remaining option is to remove the switch and enable Wi-Fi on the V6 box?
