Wifi range is really bad for a reason

Wed Jul 10, 2019 4:26 pm

So, if my phone is near the router, so that said - on my PC, the wifi signal is very good, but if I decide to go to the kitchen, which is 5-10 steps further the wifi drops very fast, even the connection is lost.

Surely you're aware that 5GHz signal drops quite quickly with the distance and doesn't run "around the corner".

With 2,4GHz is basically the same, a tiny bit better.

Which frequency you are talking about:
2.4Ghz : interference --> real issue on 2.4G, If you have lot of neighbours this kills range...
5Ghz, older devices/phones have pretty bad 5GHz performance. Newer smart phones have 2x2 5Ghz Wifi which is providing better coverage.
With that 5Ghz should still reach across one concrete wall at least.
Then what AP are you using? 4x4 5GHz does better than 2x2 or just 1x1 .. clear with a hap ac lite your 5G range will be very limited.

Im using hAP ac². That being said im using an Huawei P20 lite and yes, there's only one concrete wall between my room and the kitchen. Previously i used an old tplink 940nd and i didn't have any issues like that.

Fix the channel and change with no EU country for example Canada !

It's me again.. The problem still persist.. Sorry for the late reply, but..

When I go to the kitchen the signal strength is just awful. Even with Canada as a country.

What does the number -54 in column just left of the bar chart mean? If it's signal strength, then that's a very good signal, most of wireless devices will normally work down to around -75 ... and by "normally work" I mean they will get throughput around 1/4 of nominal speed (if nominal speed is, say, 533Mbps, then realistic throughput will be somewhere around 130Mbps).

That should be the signal strength in dB

Image

When im near the device, so said on my PC - the signal is good, the speeds too - 72 Mbps Download, 69 Mbps Upload, but when I go to the kitchen which is literally 10 steps and 1 wall the signal just go dooown, extremely poor signal witch 9 mbps down and 7 mbps, that said this is for 5mhz, if i change it to 2,4 its a little bit better but still the signal is more than bad.

10 steps and 1 wall - specially if the wall is reinforced concrete - is huge for 5GHz and big for 2.4GHz ...

What's the signal strength (numeric value) in the kitchen?

Signal strength of -85 is, as you discovered yourself, beyond the edge of usability ... So it seems you'll have to add another AP for those WiFi enabled kitchen appliances ....

So, I need to buy something to extend the signal, or ?

Preferably add another AP which would connect to LAN using cable. If that's not possible, add another dual-band AP and use one of frequency bands for point-to-point connection between existing AP and the new one. Wireless range extenders (repeaters) are worst solution because they consume air-time of "master" AP and thus reduce available bandwidth to around one half for just every wireless client.

Well, I guess i'll need help with making a new AP, since i don't know how to do what you suggested. :lol:

As I wrote: get another Mikrotik AP which has dual-band wireless. Another hAP ac2 would be great, hAP ac lite would do as well (but worse than hAP ac2 as it only has single chain 5GHz).
Then you'll have to find a spot, where signal strength of existing AP is at least -75 dB and at the same time offers good coverage of kitchen.

Then you apply some magical config on both APs to make it work (I have such a setup running so I can help). Bonus of such setup: you'll get wired LAN at the position of the secondary AP ... free of charge :wink:

Can I just use my old 940nd? Which is 2,4mhz just for AP? It still working, i just needed an upgrade. And use the 5mhz just in the room, for my PS4 and TV, 2,4 for everything else

If you will use your TP-Link, you'll 1) use same frequency for both connection between APs and connection clinent-TPLink (loosing lots of capacity) and 2) have huge problems with connectiviry between TP-Link clients and the rest of LAN ... It wouldn't even work as wireless repeater because that reliably works only when both AP and repeater are same from same vendor.

So in short: lots of headaches

Well, there is possibility to use your old 940ND: grab a pair of PowerLine adapters to create wired connection between hAP ac2 and 940ND.
