@DanAir Hi Dan!  I would verify if this is legal with your ISP??? It is not here at all.  You just need 1 router in house 1 and just use the radios to create a wireless beam and plug into a switch in house 2.  You wlll need AP's in both houses for wifi.  I would create a VLAN to separate both networks if that is what you want to accomplish.

@Doc2485 Fair point, I imagine this would breach the ISP's T&Cs, so for the purpose of this discussion, let's imagine house 2 is at the back of my garden.

How do I create a VLAN?  Wouldn't that require additional equipment?

If I set the CPE510 in house 1 to AP router mode, would that achieve the same thing?

@DanAir This may help you if you want it:

No... use 2 CPE510 radios and create the wireless beam... that is what they are made for...NOT wifi

PS: Radios need clear line of sight... no trees, buildings, etc.

@Doc2485 Ok, but this is starting to sound beyond my abilities.

I get the need to have line of sight and the only purpose of the CPE510s is to create the "wireless beam" as you put it.  I'm just wondering if there's a simpler way to prevent LAN users in house 2 being able to access the LAN in house 1 (apart from the internet connection).

@DanAir You could do this and enable Guest network to do that....but you still need a ethernet, fiber or radio connection to house 2 to share your internet from house 1.

@Doc2485 That really is what I was proposing in the following topology:

Modem - Router - Switch - CPE510 (house 1) ------------ (house 2) CPE510 - Router

I can set a guest network on the router in house 2, but this wouldn't stop someone plugging in their own router directly to the CPE510 in house 2, providing access to the LAN in house 1.  The question is how do I assign the CPE510 in house 1 to the equivalent of a wireless guest network? My router doesn't allow guest network on wired connections, only wireless ones.

@DanAir You do not want 2 routers on same network...... modem>>router >>> CPE510 >>>CPE510>>> switch and AP (some routers can be put into access point mode...but I do not do it.... I only use only AP's. )

@Doc2485  OK so this (which is what I meant actually - my mistake):

Modem - Router - Switch - CPE510 (house 1) ------------ (house 2) CPE510 - AP

But back to my question - is there any way to put the CPE510 in house 2 on the equivalent of a wireless guest network?

@DanAir No, that will not work the best way that a AP will.

If you need consulting work on all of this..PM me on here and we can discuss options.
