Hi Eric,
I’m jealous that you can get those results with the Fritz alone. And fully agree, I also do not believe the access point improves sound (other then maybe radiation onto the equipment). It only helps setting up a clean channel in a space with lots of interference. Actually, now that I know a bit better how it works, I think two 902ac units (one as access point and one as a client) with openwrt and external antennas set on a narrow 5ghz channel could most probably be a great lower cost solution to areas with lots of interference.

Hi everyone,
Here are the printscreens of my Aruba setup. It could be a good starting point.

Hi Eric,
Your post for the external antenna was also the inspiration for my setup. I’m using the same setup but with a different antenna.

Hi Rghanbari,
Here are some photos of the antenna connector on the 902ac. Looking at the back of the 902ac, the centre of the antenna connector is exactly 15mm from the top and 30mm from the left outer edges. The hole does not have to be more than 4mm in diameter. Just beware that the hirose connector sticks out more than a centimeter.
Hi Rghanbari,
Congratulations on the Aruba! I’m a bit busy today, but will share the exact location of the hirose connector and some printscreens of my Aruba setup over the next few days.

Hi Basillus,
The link works for me. Thank you for sharing. I will probably get one of these later. Please be aware that when using a directional antenna on the 902ac a change of a few degrees can change the signal up to 10 dB, or make the orientation such that the antenna becomes sensitive to room activity. For example, if someone walks through the room, you might get a change in signal reflections and this can impact the retries big time. It is exactly for this reason I’m using my daughter’s old Lego, so I can build the base where I can change the angle of the Aruba as well as of the directional antenna to get the most stable signal between the two. I tried wall mounting, but I always get better results when the Aruba is not parallel to walls. Keep in mind that Aruba has the strongest signal at 30 degrees down from horizontal and my test proved this angle does work the best….in my case it is tilted around 30 degrees down and around 3 to 5 degrees in the horizontal plane. For me, setting up the directional antenna and getting good results was a very long and a frustrating process. I never tried it, but getting an omnidirectional antenna could also work and might be easier to dial in. I did a setup with two directional antennas using their t-adapter. It did make the signal stronger by about 3db but it was also less stable. On the other hand, this same dual antenna setup could work when using 2 omnidirectional antennas. Here is the link to this duomax adapter where you basically connect two identical antennas to a single pigtail cable. https://frixtender.de/shop/frixtender-duomax-sets/

Hi Rghanbari,
It is the PS4 directional antenna with the hirose pigtail. Here is the link to the antenna: https://frixtender.de/produkt/frixtender-p4-schwarz-2/
Hi Eric,
I’m case you meant Bosko, then yes, I use an external directional antenna for the 902ac. It gives around a 10db boost. Actually, I am testing a new orientation and the 902ac antenna power is set to zero dB.
Hi Basillus,
Thank you for sharing. Interesting to see that he came to the same conclusion about the 5 GHz frequency with a narrow channel as the best option! Though from a different perspective. For me it was the option with least interference and least retries. It’s a nice benefit to know it is the option with least impact on all the components. Will check the firmware he is using. Actually, now I’m debating whether to get the Aruba 324 (sister model with external antennas) and do a test with a directional antenna on both the 324 and the 902ac to reduce the interference from the surrounding and to the equipment even further.
Cheers,

Hi Eric,
Regarding 5ghz on 902 AC. I have the V4 and I recently updated to the latest openwrt 24.10.4 firmware. It supports 5ghz natively and works without an issue. Maybe this helps.

Hi Eric,
You are right, I also have a Fritzbox as my main router, and have been doing exactly that until a few weeks ago when I found out about this network isolation option on the Aruba. With the Guest option i could never isolate all the devices as some of them, like a security camera, nvidia shield… needed to remain on the main network. Now when it is 100% isolated I can’t say I hear any sound difference between the 2 options. It just makes me feel good:)

Hi Eric,
The dejitterit portal was simply beneficial as the proprietor extensively measured end explained why he uses the ARUBA IAP 325 in the modified kit he sells and why wifi 5 (ac) is the last „non-harmful“ (to cabling and equipment) technology. Luckily the Aruba and the AC902 use the ac wifi 5 technology:)
Also, if someone has only one access point in their listening area then the way to set it up is to create two SSIDs on this AP, one on a 5GHz and one on a 2,4GHz channel and give them separate credentials. Then use one of those SSIDs to connect to your TP Link and the other one for the phone (the controller). This will have no wifi interferrence as each SSID is on a different channel.
Actually, the Aruba has a really cool feature – one can block broadcasts from devices in the network. In other words, in my setup, the only broadcast that arrives to the TP Link is from the Roon server. Everything else is blocked. Even the phone (the controller) only communicates to the roon server. I literally have to give it clearance if I want to modify something on the TP link.
Cheers,
B.
