Model: CPE510  
Hardware Version: V2
Firmware Version:

Hello everyone.

 

I'm currently trying to get three CPE510 to work together in order to expand wifi coverage.

 

The modem is connected to the switch (and works fine, I get internet when I connect the PC to the switch).

And there is another wifi router also connected to the switch (also works fine).

 

The first CPE510 is in bridge mode with the IP 192.168.0.254 and works fine. But when I connect the second CPE510 (also bridge mode, probably not the best choice right?) and assign the IP (tried 192.168.0.253 and even 192.168.1.254) it looks like the DHCP server kinda breaks and I can't get IP on any router.

 

What can I do to fix this? I'm definitely doing something wrong, but don't know what.

 

Thanks for any further help.

It is better to configure Client mode on the 2nd AP.

 

What do you mean when you say "it looks like the DHCP server kinda breaks and I can't get IP on any router." Do you try to connect some router to your 2nd CPE?

 

You are talking here only about 2 CPE, while you mentioned 3 of them.

 

CPE510 has directional antenna, so repeater mode is useless, so you will not be able to properly expand your wifi coverage. These devices are used not for expanding wifi coverage, but for transmitting signal by wifi on long distance. It is P2P, rarely Point-to-Multipoint, but not some Base Station for clients.

Hi, thanks for response.

 

I say that the DHCP server breaks because once I connect the second CPE to the switch, the first router (another model) and of course the second CPE, both emit wifi signal but I get the APIPA addresses, which will not happen if only one CPE and the other TPLINK are connected.

 

For clarification, I have three CPE, but only managed to get two "working".

The third one, I didn't even try to configue it since I can't even get two working 100%., but the plan is to have three CPE connected and emitting wifi signal (being a total of 4 wifi routers, 3 CPE, 1 another model)

 

Another thing that might be a problem is that the first wifi router that is not a CPE, has some private class A IPs and the CPE have the C Class IPs.

 

Hope I could clarify and express my intention a bit better, please don't be afraid to ask more information about the setup.

And again, thank you so much for the help.

It doesn't matter much, what IP-addresses are on CPEs, if you use L2 Modes (Bridge, AP, Client) and you don't use AP Router or WISP. CPE's IP-address is only for its management, while DHCP should go without problem. Of course, it is better to make everything in one subnetwork, so if you configure A-class on Router, you still can manually configure A-class for CPE also. However, I repeat, it should not affect clients somehow. I would try to configure static IP on the client of 2nd CPE. Also I would check SNR between two CPEs, so it is good (at least more than 20db). Just in case you can check and change IPs on both CPEs, so it is different and it belongs to subnet of the router.

You did screw up your network by using CPEs in bridge mode. The CPEs are not routing in this mode, they are bridging.

 

Another thing that might be a problem is that the first wifi router that is not a CPE, has some private class A IPs and the CPE have the C Class IPs.

 

CPEs support class-less IPs. Of course you can use them in a (legacy) class A network, just set the correct subnet mask.

Alright, I will try to get everything working with that modes.

 

If problems arrive, I will configure the CPEs on the same class as the other router.

 

Hope this finally works, thanks once again.

@R1D2 

Well, that indeed might be the problem maker of all this...

 

And very helpfull to know that the CPEs are class-less, helps on the fixing this.

 

Thanks a lot.
