    How do I connect 3 buildings using CPE510 hardware

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    I have 3 building locations on my property - currently I have an Internet connection and wireless network in Location 1 - I want to extend the network and internet access to the other 2 locations.

    Location 2 is approximately 600 feet from Location 1 and has good line of sight with no obstructions

    Location 2 is approximately 2000 feet from Location 2 - it has good line of sight from Location 2 with no obstructions however there is no line of sight between Location 1 and Location 3 - there is a hill between these 2 locations that is heavily treed.

    Can I use 4 of the CPE510 units in 2 pairs to extend the network and internet from Location 1 to Location 2 and then from Location 2 to Location 3 in sort of a daisy chain configuration ?

    Any advice or input on this will be appreciated.

    thanks

    Makes no sense. But I got it, you want to chain Location 1 with 2 and 3, right?

    Should be no problem with 4 devices and two different WiFi channels. On Location 2 you can even power the two relaying CPE510s with the same power supply and feed the PoE through the second port of a CPE510, so you need only one cable to the outdoor CPE.

    thanks for the reply and sorry for the typo - should have read "Location 3 is approximately 2000 feet from location 2"

    What mode would I configure the hardware for the link from Location 1 to 2 and location 2 to 3 ? All in Bridge or some other configuration ?

    Can I install a wireless router configured as an access point at location 2 and bring the Ethernet cables from both of the CPE510s at that location into the LAN ports to transfer the signal between the two 510s as well as provide wireless access to the network inside Building 2 location ?

    thanks

    I would not use bridging mode except you really need only one broadcast domain over all locations. Usually in a setup with several interconnected networks the CPEs are set to AP mode (CPE #1/3) and client mode or AP client router mode (CPE #2/4). The user guide explains the possible operation modes for different use cases very well, you should take a look at chapter 2 / page 4 to 9. It is very helpful to find the best operation mode of the CPEs.

    Can I install a wireless router configured as an access point at location 2 and bring the Ethernet cables from both of the CPE510s at that location into the LAN ports to transfer the signal between the two 510s as well as provide wireless access to the network inside Building 2 location ?
    Sure. You don't even need a wireless router, an indoor AP at location 2 would be possible also if either CPE #2 does the routing (in AP client router mode) or CPE #1 forwards routing information to location 2 (in an AP/client setup).

    thanks very much for all the help R1D2 - I will be purchasing the hardware after Christmas and starting the install.

    Also in the process of 'venturing' on a similar wireless project, currently in the final stages of receiving some missing parts, so I'd expect this to materialise over the course of the next two weeks. Already have a solid link between two of the three sites that need be connected, so keep following for a detailed report as it all slowly yet surely finalizes.

    Hi,

    I'v just put together a network of 4 CPE510, like R1D2 suggested, 1 and 3 as AP and 2 and 4 as clients, I'm not sure about "4 devices and two different WiFi channels", R1D2 do you mean Channel Width in wireless settings ?

    No, I mean "Channel/Frequency" in wireless settings. Two pairing devices use one channel, the two others use another channel.

    Ok I have sorted this setting also, on your youtube demo of cpr510 you recommend scanning the frequency for quality, in the graphic are 3 lines yellow, red and blue, red an yellow are pretty much the same in all channels but blue is spiking up in some , is this meaning that the channel has interference on it ?

    And just for a future development of my network, is possible for an AP cpe510 to serve two ore more clients cpe510 if all of them are in range ?

    Yes. Could be caused by another AP or a weather radar operating in the 5 GHz band (depending on where you live) or anything else. Blue means "peak", red is "current" and yellow (actually sand-brown) means "average" level of signals/noise. But it's not my YT video, I'm just a user of TP-Link gear.

    This is a snapshot of a spectrum analysis I just did on my CPE510. Best frequencies (see arrows) would be around 5.480, 5.520, 5.600, 5.640, 5.680 and probably 5.560 GHz. But 5.480 GHz (channel 99, red arrow) isn't allowed in my country for WiFi, so I have five channels with very low noise, namely channels 104, 112, 120, 128 and 136, where on channels 116 to 132 radar could appear then and when, so I would avoid those channels if possible.

    And just for a future development of my network, is possible for an AP cpe510 to serve two ore more clients cpe510 if all of them are in range ?
    Sure. This is called Point-to-Multipoint (PtMP) mode. The CPE510 also offers MAXtream, a time-multiplex technique to ensure that every CPE client get's an equal amount of AirTime, thus minimizing interferences of the CPEs on the same channel (you can't use different channels if all clients are connecting to the same AP).

    But you should pay attention to the antenna's beam width of the CPE, which is 45 on the H plane and 30 on the E plane. Therefore, if you want to distribute a WiFi signal in a wider range, you should consider use of the WBS510 with a sector antenna such as the TL-ANT5819MS, which offers 120 antenna beam width. See picture below for a typical PtMP setup using 3 CPEs and a WBS with sector antenna. The WBS510 runs under the same operating system as the CPE510 does.

    Hi, I'm back i finally installed the CPE510, only the first pair,the actual setup is 1,5 km distance with a height difference of cca 80 m and now I'm in the middle of proper alignment (right now by best signal strength is -67 dbm) but I found a problem, if my client disconnects will not auto reconnect, is a setting somewhere that I misted ?

  12. #12
    Do you use fixed channels? Did you wait long enough for a re-connection? What caused the disconnect?

  13. #13
    Actually i did a spectrum analysis and the connection was lost, I just checked the connection and now is up and running.So I ques reconect took longer than I was expected

    Reconnects in the 5 GHz band can take a while.

    Hello, I have some trouble with getting align the second pair,Name:  20170506_194322.jpg

Size:  53.9 KB as you can see in the picture first antenna, set as AP is on the top of a hill mounted on a post and the second one is at the bottom of the hill an a post too, visually there is a direct line of sight between them but I could not make the Client to connect to the AP, distance is 411 m

    The hill dose not have a regular slope, it has a bulge ( that's why only the post is visible in the picture) but as I said before direct line of sight is available.

    For a brief moment I succeeded in connecting the Client to the AP , I hat excellent signal strength cca -58 dbi but the connection was no good, when pinging the AP I got TTL form 1 ms to 1000 ms

    What could I do to make it work?
