Hi Breno

You can check the wired devices wether can get the correct speed. After all, when the devices is connected to the router directly, the testing result will be more acurrate. 

I could, the only problem is that it is happening to iOS devices, my tablet and phone are the ones that have been going through the issue. Reconnecting the wifi doesn't help but restarting the AP seems to fix it for a while. I can try to reproduce it on my mac, and when it happens connect via cable to the router, I'll try that and post the results here. Strangely, that didn't happen before I installed this router.

Your topology war Router----wireless clients before. Now your topology is Router----AP----wireless clients. So if you use the same topology of Router----clients to do the test, you can check if the problem is related to router or AP.

I bet it is about IOS<->AP. Try to change wireless channel manually (6), change wireless bandwidth to 20 MHz (old IOS devices work poorly with 40MHz).

I can only get 0.5 mb of download bandwith afterwards on that device, when I should be able to get at least 4mb with my bandwidth control settings.

 

Also check this, just in case if you are not familiar much with networking. 4 Megabits equals exactly 0,5 Megabytes :)

Hi Mitya, I have made some more tests and I strongly believe now that the problem is the D-link Router converted to AP. Yesterday, my connection almost stopped on both the macbook, iphone and apple TV, at the same time. I managed to restart only the AP, and it fixed the issue without even needing to log in to the router.

But I'll try those settings on the AP and see if it works, I don't have an old device though, I had this issue with an iPhone 7 Plus, and I just got a XS Max, definitely not old haha.

I am familiar with networking, that's why I wrote "mb" and not "MB", as Mega Bytes are usually written in caps and networks are measured in megabits, when I say 0.5 mb, I really mean 0.5 mega bits, 65 KBps (like a dial-up modem)!

Thank you for the heads up on the wirelless settings, I'll try those and see if I get better results!

Just to close the topic, I ended up switching away from that old router-converted-into-AP, and bought a TP-Link EAP 225 Omada - A bit overkill, but it does the job really well.

One of the reasons I did this is due to the tests I made later and this very forum, TP-Link support forums have been really good and you all have been really helpful, while the other manufacturer simply discontinued the product and offered no support - even though they said I had 5 year warranty when I bought it.

So thanks a lot for the tips and the attention!
