Router was reset to Factory Defaults. Upgraded to 27506. All settings are done according to the instructions by KrypteX.
Result: 5Ghz speed was not changed, router keep losing 5Ghz wireless every hour.
Tested on iPhone6 plus HP notebook with wireless card using latest driver.
I'm open to any other suggestions Smile

Which channel are you using now ? Have you tried all 4 combinations as I described above ?
Disconnect all Apple products from 5G and leave only the HP laptop connected on 5G. Are there still issues ?

I tried with Channel 56+Lower or 52+Upper.

153+Lower or 149+Upper does not appear on my router.

I have options between 36-5180Mhz and 140-5700Mhz

iPhones were disconnected. Currently it seems the 5Ghz speed is equal to the 2.4Ghz on my router.

Set Regulatory Domain = Canada or United States and you'll have upper channels 149+ too. I've already told you to do that, won't say it again.

Hm, sorry for the domain miss. I was sure it was US, but it changed to Germany at installation time.

Anyway, I changed it to Canada and tried the other 2 frequencies. Unfortunately those 2 gave me even worst performance, only about 20Mbit.

Can you provide some snapshots of your Wireless settings, including the Advanced ones, for both 2.4G and 5G ? Something's not right, 20 Mb/s is too slow.

Here are some screenshots.

I had to revert to 27456, as 27506 kept losing 5Ghz wifi at about every hour (2.4Ghz was not affected)

Use AES (not TKIP) for WPA2 Personal WiFi security. I think that's the main cause for the WiFi slowness.

Additionally, don't set Auto channel, but manually chosen one (e.g. 6+Lower on 2.4G and 56+Lower on 5G). And HT40 for both (not HT20).

Ok, the change for the security from TKIP to AES worked. Speed is over 100Mbit on the 5Ghz now. Thanks a lot!

You're welcome. Just curious, what's the max speed you can reach on WiFi now ? (you said you have a 200/100 Mb/s internet) You can test with speedtest.net, for example. But please test with a laptop with good WiFi card (N300-capable at least)

If you are at it, could you also test the same on a LAN cable, instead of WiFi ? Just want to have an idea of the WAN-to-LAN NAT capabilities of this router model.

My iPhone6 is doing 82 Mbit download / 99.9 Upload at the moment. I'll check the notebook tomorrow morning.

Maximum speed achieved by my HP notebook with Intel Wireless-N card: 115.75Mbit / sec download speed, 103Mbit upload.

OMG guys, please stop fighting Smile

About the question from KrypteX for the LAN speed:

"If you are at it, could you also test the same on a LAN cable, instead of WiFi ? Just want to have an idea of the WAN-to-LAN NAT capabilities of this router model."

Actual LAN speed is 203Mbit download / 102Mbit upload, on a PPPoE connection coming on a fibre cable to my house, ended up by a Huawei device, which provides Internet, telephone and TV.
Theoretical speed of this net is 200/100Mbit, but the provider always give me a bit higher speed.

I am thinking to upgrade to 500/200Mbit speed, should this router quick enough for that?

Thanks for testing it !

On WAN-to-LAN it might give you more than 200/100 (which is your current max speed from your ISP), but WAN-to-WiFi will remain as it is now (around 110 Mb/s).
