How to get 2.5Gb/s

Bianpie · 2025-09-19T12:28:53+00:00

Qualche tempo fa ho chiesto aiuto per rimpiangere la connessione della scatola di connessione 3 con il mio router ASUS Mesh. Alla fine mi è stato consigliato di acquistare un interruttore di ubiquità per connettersi alla porta 4 di connettere la porta 4. Sfortunatamente sono passate molte settimane e non vedo alcun miglioramento. La mia domanda: in base alla tua esperienza, quale router mesh+satellite potrebbe funzionare meglio con la scatola di connessione 3? Avrei cogliere l'occasione per l'aggiornamento a WiFi 7. C'è qualcosa che deve essere controllato per assicurarmi di ottenere completamente i 2,5 GB/s? Grazie mille

Some time ago I asked for help regrding the Connection of the Connect Box 3 with my ASUS mesh router. Ultimately I was advised to buy a ubiquity switch to connect to connect box’s port 4. Unfortunately many weeks have passed and I do not see any improvement.
My question: based on your experience, which mesh router+satellite could work best with the connect box 3? I’d take the opportunity to upgrade to WiFi 7.
Is there anything that needs to be checked to make sure I fully get the 2.5Gb/s?
Thank you so much

hello Bianpie

I do remember the conversation we had regarding the speed issue.

The Ubiquiti switch is proven, not to affect the speed provided on Port 4 of the Connect Box 3. Pointing out the switch wasn’t a shopping advice.

Yesterday I did take my home-network apart, removing one of my WiFi AP’s (Zyxel NWA130BE), to do some testing with the Connect Box 3.

With a MacBook Air 13″ 2022 M2 I got like 850-900Mbit/s on the Wifi-Connection. The WiFi Connection on the MacBook showed 1.2G and it was on the 5GHz band.

The test on a Samsung S24 showed speeds up to 1.63 Gbit/s. The 6GHz band was used for this test and the device showed 6e.

The only time, I got full speed, was when I tested on my PC with a 2.5Gbit/s NIC over LAN cable. On all tests there were two managed switches (Zyxel XGS1210-12 v2) and an unmanaged switch (Zyxel MG-105) between the Connect Box 3 and the PC or the AP.

There might be other network equipment, working well with the Connect Box 3. Like i said, Ubiquiti and Zyxel devices have shown, not to affect the port speed of the Connect Box 3. Some devices from other brands impacted the port speed dramatically, almost reducing it to less then 100Mbit/s.

WiFi connections tend to be very unstable, when it comes to speed. Sometimes it’s good, sometimes fair or even poorly. There are many things that can play into the quality of the signal.

The only proven way, to get most of the speed, is using a computer with a build in NIC that is capable of 2.5Gbit/s or more.

Xydocq Thank you so much, you are so helpful!
As recommended, I bought the Ubiquiti; i connected it to the box 3 and on the other side i have my mesh router ASUS.
I’m trying to figure out how to get the same LAN speed from my mesh router as I do from the LAN connected to the box 3. It seems like when I connect the LAN directly to the box 3, I get speeds over 2Gb, but when I connect it to my router, even with the Ubiquiti in between, I only get half of that speed.

could you please provide some information how your network setup looks like.

My setup looks like this:
Internet - Connect Box 3 (Router Mode) - Switch 1 - Switch 2 - Zyxel Router (DMZ) - LAN Switch - WIFI AP/Computers

Or if possible a sketch

Those are just examples.

Bianpie

Xydocq First if all many thanks, very kind from you to interact on a saturday afternoon.
Actually my set-up is exactly like yours, except that in my case from the ubiquiti i only have one wan which connects to the ASUS

Xydocq

Bianpie your setup looks like the sketch?

If yes, you have this option without getting any new equipment:

Run the Connect Box 3 on Router Mode. Disable the WIFI on the Connect Box 3.
Connect the Ubiquiti switch to Port 4 of the Connect Box 3.
Change the operation mode of the Asus router to Access Point/AP-Mode and connect the WAN Port to the Ubiquiti switch.
Plug the Computer into another Port of the Ubiquiti switch

Now your Computer will have a faster connection and your Asus router has the same speed as before. You can still connect devices to the Asus router but they will only get 1Gbit/s. Only the Ubiquiti switch will share the faster speed.

Bianpie

Xydocq This is amazing, never thought about using the box as router. Awesome, I’ll set it up as you described. Enjoy your weekend!

Bianpie

Xydocq Friend, I have done all you said. Connected box 3 with ubiquiti and then ASUS, all using the 2.5B ports. I ran a speed test using the ASUS itself (so no connections, no wifi…) but i get only half. What could it be?

Xydocq

hello Bianpie

I wouldn’t worry too much about this.

Even tough a device has a 2.5Gbit/s port, doesn’t mean it will make full use of it, here are some examples:

Cisco Meraki Go GX-20 1Gbit/s port, max troughput 250Mbit/s
Zyxel USG Flex 50 1Gbit/s port, max troughbut 260Mbit/s
Zyxel USG Flex 200 1Gbit/s port, max troughput 650Mbit/s

I can’t find any information on the real troughput of the ASUS router you have. My XT8 got a max of 1.6Gbit/s on the Connect Box 3 and with my WiFi7 AP using the fastes WiFi device at hand it was max 1.61Gbit/s. No other device I have supports WiFi7, so they are way slower.

I am a customer, just like you. I’ve had many different devices in use. I can talk about the devices I’ve had but I am not going to buy devices, just to test them. Nor should you.

To make full use of the 2.5Gbit/s is almost impossible. I monitor my connection and the most download speed I use, is around 170Mbit/s. That’s when my server runs a backup-task. During normal use the most is 30Mbit/s. Most of it is used by the TV-Boxes. Also, the server you download from, needs to support the speed. Since bandwith is still expensive, most don’t.

Bianpie

Xydocq well, you have been so kind and helpful, i do not want to abuse your patience.
I hoped that all 2.5Gb wired connected box 3 -> ubiquiti -> ASUS XT 8 I could read some higher speed on the XT 8 itself, as there is not wifi or anything else in between. I’m running the speed test provided by the router itself, so no further connections (when it goes to wireless i accept a drop, no problem).
Should i buy a new router with a better 2.5Gb port or 10Gb port, so that the 2.5Gb effectively arrive at the router?
Please enjoy your Sunday

I did some testing with my XT8. But first, you don’t run the Asus router in AP mode, it is still set to run as Router. The speedtest isn’t available in AP mode.

Anyway here are the results:
Baseline-Test 2.5Gbit/s NIC on Computer

Now the ASUS XT8 running on Router Mode:

I also got results around 1300Mbit/s so it was almost everything in between.

Now the MacBook air on the Asus WiFi:

the MacBook Air maxes out at the speed of the wifi-signal. So it doesn’t say anything about the real speed of the connection.

Bianpie

Xydocq You are absolutely right, I had to revert back to router mode to run the test. Well, I still find it funny that sunrise comes in with well above 2 Gbit and the ASUS can onlyget to 1.8 (in my case 1.3 max).
I was wondering if this is an issue with the ASUS or elsewhere.
Enjiy your sunday evening

Please log on to your Connect Box 3 and have a look at Admin > Information.

Tell us what Software version your Connect Box 3 runs on.

Daniele_Sunrise

Bianpie Everything is set correctly on the signal side. I can imagine that network scanning services on your router are slowing down the traffic. I have this tip from the Internet. Another question is whether you are using an antivirus program and if so, which one exactly?

“If you recently encounter limited speed acceleration, or unable to reach maximum connection speed, please try to disable the following features: AiProtection, Traffic Analyzer, Web History, Adaptive QoS, Game boost, Web & apps filters, bandwidth monitor, Mobile Game Mode to maintain the optimal internet speed.”

Bianpie

Xydocq here we go…and a big thank you once again

Xydocq

Bianpie

Your Connect Box 3 sports the same software version as mine.

Maybe @Daniele_Sunrise can take a look at your connection.

Daniele_Sunrise

Bianpie Please send us your customer number, address and date of birth via private message for processing. We will then be happy to check the configuration of your modem.

Greetings
Daniele

Bianpie

Daniele_Sunrise I did reply with DM, hope you received it.
Thank you!!!

Bianpie

Daniele_Sunrise First of all thank you so much!
I checked all I could but cannot find the bottleneck; AIProtection is off, no QoS…
The connection is box 3 -> Ubiquiti switch -> asus router, all connected with 2.5Gb ports.
Today i measured the speed using my router Asus (so no wireless in between): to my big surprise, I got 1.7Gb, so 0.3-0.4 more than usually…
If there is anything else I can do to make use of the 2.5Gb connection please let me know. Is a new router an option?
Thank you!
