AX86U Antennas

[shawnpear]

Lost my antennas while shifting house. Anyone knows if I can use ac86u antennas with my ax86 router?
Or will I lose out on some performance

Or can I just use any other suitable antenna? Like a 12dbi one.

Use the antennae the router shipped with for best results. (Ask Asus for replacements).

Changing the antennae to a 12dBi (or other) model will change its radiance pattern. Which may be changes you don't want, need, or expect.

Yes, me. You can use AC86U antennas. AX86U will work in exactly the same way. Tested, see my signature.

Useful info, just to furthering antenna's question... does you know each antenna of AC86U/AX86U what band will manage?

 

[L&LD]

Both 2.4GHz and 5GHz bands for each antennae.

just to furthering antenna's question...

The 3x external antennas are mostly for marketing purposes. Standard dual-band low gain dipoles close to sphere omnidirectional. The actual antenna part inside the plastic is about 5cm long. The 4th antenna is internal printed on a small PCB.

Thanks for the info. But in other post someone said the 4th internal antenna manage only 5ghz. So External will be 2.4/5ghz (3x3) and internal only 5ghz (4x4), right?

It's clearer now, so the 4th Antenna has less performances than external 3 one's? I don't understand how as example MI-MO can manage a 4th different antenna without loosing performance with clients when 4x4.

 

[L&LD]

Yes, 2.4GHz is 3x3:3 and 5GHz is 4x4:4.

But you only asked about the external antennae.

The internal 4th antennae doesn't have less performance. It is equal. And, furthermore, it is matched to the external antennae otherwise it would decrease the overall performance, not benefit it.

No, the router will work in a very similar way with 4x printed internal antennas. The sticking plastic outside serves mostly marketing purposes. How many business access points you have seen with external antennas? This is what antennas on a high-end access point look like:

No one have external antenna's, that's true.

@L&LD @Tech9 Pretty off topic but can you share in your experiences the better overhall high-end Wi-fi Router/AP for 3-story house?
Anything i tried struggles behind 1 Wall at 3 meters away from router... that's why i was asking about internal antenna's performance on AX86U as my main problem are 5ghz wi-fi ping spykes.
I can only say AX86U-Pro, AX88U and GT-AX11000 share the same problem in my house, 5Ghz just struggles.

It's the house, not the routers. You need multi-AP system to solve the problem. You perhaps need professional help. Online forums are unlikely to help. You can only get general advice. Someone who knows has to come and see what the problem is and suggest/install the equipment needed to solve it. You obviously need something better than single home AIO router.

You are in Italy, the houses there are solid brick and concrete. Your Wi-Fi channels availability is specific and transmit power is different on different channels. I have a house in Spain with the same Wi-Fi problem. I'm using 4x Cisco APs on low power, the walls kill Wi-Fi. No home router works well there. I know what the problem is, but there are too many variables in the equation.
