Hi,

At home we have a Cisco EPC3928AD EuroDocsis 3.0 modem, supplied by our cable company Ziggo. Wired connections work great (178mb/s download on Speedtest, contract is 180mb/s), but all our mobile devices use Wi-Fi, laptops, phones, iPads, you name it.

For the last few months, we continuously have Wi-Fi problems and we've attempted some things to solve our problems.

The three problems we are facing:
- 5GHz has not got enough range to go up one floor, only thing between router and device is the ceiling / floor. We have a Linksys RE2000 wireless extender that only spots our 5GHz network half of the time.
- 2.4GHz does not connect half of the time. We can see the network, it refuses to connect and gives us no clear reason why.
- Once 2.4 GHz works, we have no internet whatsoever.

I have used the Wifi Analyzer app on my phone, and I get the following graphs:

As you can see, in the first screenshot, you see two 2.4GHz networks named "Rutten2.4GHz", one is our wireless extender and the other would be our modem/router. Seen in the second screenshot, we are the only 5GHz network in the neighbourhood. I was connected to our 5GHz network at the time I took the screenshots, and you can clearly see I only have one bar of signal strength. My iPad, which is positioned exactly next to my phone, does not see the 5GHz network at all.

So far I have attempted changing the router's bandwidth, it is 40MHz default, I changed it to 20MHz but it does not seem to help at all. I tried setting our router to a fixed channel, but other channels constantly hop from one to the other so this would cause more problems.


So, judging by my graphs and the problems I described, what are things I could try that would make sense? I'm doubting if I should buy a router that has more strength (which?) and try to suppress other networks around us, or are there other tricks to improve Wi-Fi quality? We attempted to call our cable company before and they sent over a technician, who changed some things in our router (set us a fixed channel, changed the bandwidth) and the problems were solved for not that long.

I got suggested buying a ASUS RT-AC66U, would this be recommended?
