I am having some serious issues with the Deco S4. I live in a bungalow and my ISP router does not give out great WiFi to adjacent rooms. So I purchased the Deco S4 to help solve this. The internet speeds since day 1 of purchasing have been terrible. The speed fluctuates so much.
Here is how they are set up in my bungalow:
As you can see the distance between the Deco units is not very far. I belive this is down to the internet speed coming from the main deco unit.
I have it connected directly to the router. My ISP speeds are:
I have updated the units to the latest firmware. The WiFi analyzer shows that the network is good however the DecoLab shows that the devices are using the wrong channel as they are using channel 5 and the clearest channel is channel 13. I have no way to change this.
I have tried the guest network as mentioned in troubleshooting, made no difference.
I have tried the 5GHz only and the 2Ghz only, again no difference.
Disabled uPNP, port configuration etc... no difference.
I believe this is directly from the main deco as this is the deco that is showing slow speeds and is connected via Ethernet I am not sure how I can troubleshoot it.
Here are some speed tests from the main deco:
And a speed test via speedtest.net and Google on Ethernet through my PC:
Any help would be appreciated. I have done a full reboot and reset also.
