Issues with wifi, connectivity, DHCP
Hello,
3 weeks ago I got an offer from Orange for FTT*. Optical converter, Orange Zyxel router (with wifi switched off) and Deco S7 unit are in the garden house as it was more convenient since the FTT is in our location on el.distribution poles.
From the garden house it is around 20-30 metres to the next Deco S7, which is located upstairs window in typical large semi-detached house, with perfect visibility between Decos.
These two Decos create a network SSID "MC9".
The house is large and so I have installed 2x WR840N, both as repeaters for MC9 network - one in left side of the house and one on the right side. Both these repeaters are there to provide Ethernet connection for Orange TV settopboxes. And also for indoors other clients (iphones, androids, laptops, nothing special).
There were big problems from the beginning. Unreliable connections, unable to connect, no IP assigning, TV issues. After trying like almost everything, it started working for 4-5 days. Until another iphone connected to the wifi and problems started again.
I am IT person, working as PHP,Mysql... web developer. I have also installed various wifi networks in difficult places in the past.
The only thing I have not yet tried is changing the DNS to 8.8.8.8 / 8.8.4.4 in the main Zyxel router for DHCP clients (the only DHCP client is Deco S7) , when I do this I will also switch off NAT and QoS in the Zyxel since Deco is doing all this. And maybe also lower the firewall settings in the Zyxel. But not sure if Deco is secured enough.
8.8.8.8/8.8.4.4 is set in the wifi settings for Decos clients.
I can put the list of everything I did, but it was nearly everything from assigning IP addresses, trying QoS settings, beamforming on/off, mesh on/off. Network optimization function is risky, since one time it assigned channel 1 and the signal lost but I was lucky to barely connect and run the function again to get channel 5.
I was really expecting this to be trouble free, since it is just a garden with few trees and house with visibility.
Dont let me down on this TPLINK!
