Ethernet backhaul over TP-Link 5GHz N300 Long Range Outdoor CPE
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Today I started with a mesh network of four Deco M9 Plus in my house. On one of the satellite Deco's I have connected a TP-Link 5GHz N300 Long Range Outdoor CPE that is outside the window pointed at another TP-Link 5GHz N300 Long Range Outdoor CPE on my barn about 70 yards away. On the barn N300 I have connected an older non-TPLINK router supplying WiFi to the barn with a different SSID than the SSID of the Deco's in the house.
I got a pack of 3 Deco X55's and this morning I added them to my Deco network in the house and made one of the new X55's the MAIN DECO unit. At this point I had 7 Deco's in the house and things appeared to be working fine.
About 6 hours later I took down two of the old Deco M9 Plus units as I only need five to cover the house. I went out to the barn and disconnected the non-TPLINK router from the N300. I then connected one of the M9's to the N300 there. After a while the M9 did come with the green LED and the Deco app showed it as connected. But shortly after that all hell broke loose.
One of the new X55's suddenly went offline. I power cycled it but it came back up red. The M9 in the barn went down too. My laptop connected to the new MAIN X55 with a mosh ssh terminal connection to work would just constantly show disconnects every 10-20 seconds for a few seconds at a time. Another person in my house had a Zoom disconnect. The satellite M9 on the house side of the N300-N300 barn connection would show offline but flip back online constantly.
I went to the barn and disconnected the M9 there and hooked back up the non TPLINK router. I had to power cycle several of the Deco's in the house. Also had to reconnect the M9 I had in the barn back on in the house. Now we seem to be back to a stable situation like we had in the morning.
Is there a reason what I did would not work and cause the problems I saw?
@perain Hi, welcome to the community.
After changing Deco X55 as the main Deco, is your network layout like this: All Decos are on wireless Mesh Backahul, except for the CPE bridged M9 plus?
(Please check the signal source of each satellite Deco on the Deco APP to see which unlink Deco they are connected to.)
Have you noticed the main Deco X55 ever turned red during the disconnection?
If possible, we could temporarily disconnect the CPE bridge and Barn Deco M9 plus, only leaving 3*Deco X55 and 1*Deco M9 plus to see whether they could maintain a stable Mesh connection inside the house.
If satellite Deco X55s still randomly got offline and turned to flash red, the CPE long bridge connection would not be the problem.
Thank you very much.
