Both Ethernet and Wifi (2.4) speeds capped at 50-100mbps

[DaMan]

Hi, we upgraded our subscription to the Gigabit Deal last week and got our new Connectbox delivered.
It was properly set up with the POA splitter that came with it installation went smoothly until I started running tests on my phone and computer and found that unless I’m on the 5Ghz band(on which I’m getting about 700-900mb) I can’t get a speed above 100mbs as if it was somehow capped.
Even wired I tried using 4 different Cat5e ethernet cables that I had laying around.
Tried checking the duplex settings on my computer and a don’t even have the option of a 1000Gb.
Hit reset multiple times and nothing changed.

I then gave up and bought a new ethernet cable (cat7 to be extra sure) and plugged it into an Asus DSL-AC55U Router that I have I Can see that it is indeed getting the full 1000Gb on the Connectbox’ settings portal but even my router turned to be doing the same thing the 2.4Ghz band is still caped at 50-100mbs.

I just don’t know what to do anymore…

PS. Terribly sorry for the English post I just figured my broken Dutch would hinder communication 🙂

A 50~100 Mbps download speed is normal for 2,4 GHz using 802.11b/g/n.

Hi thanks for answering.
The modem has WIFI6 would that change things ?

[tobiastheebe]

Using Wi-Fi 6 (802.11ax) you should be able to achieve higher download speeds on 2.4 GHz, this must be supported by your devices, however. Using gigabit ethernet, the maximum achievable download speed is ~950 Mbps.

[DaMan]

Yes I'm aware and my computer supports WIFI6 and on the 2.4Ghz I still cant go above 100mbps.

[tobiastheebe]

Your computer appears to be establishing a Wi-Fi 4 (802.11n) connection on 2.4 GHz frequency band instead of Wi-Fi 6 (802.11ax). For Wi-Fi 4, 100 Mbps is an excellent result. In order to optimally utilize the download speed offered by Internet Giga (1070 Mbps), you should be using (gigabit) ethernet, 5 GHz is the second best option. Which NIC types does your computer contain?

[DaMan]

I can definitely see on my control panel that my connection is on WIFI6 and besides even when I plug in an ethernet adapter I still cannot go above 100mbs.

[tobiastheebe]

These are two separate issues. Please answer the question in my previous reply. Fast Ethernet (100 Mbps) will max out at ~94 Mbps. Which control panel are you referring to? Consider posting one or more screenshots.

It's a MediaTek Wi-Fi 6 MT7921 Wireless LAN Card

[tobiastheebe]

The MT7921 does support 802.11ax at both 2.4 and 5 GHz. Maximum theoretical speed at 2.4 GHz is 574 Mbps, according to this page. I would expect ~400 Mbps maximum 'real-world' download speed.

I still suspect a 802.11n connection is being established on 2.4 GHz, which would explain the download speed being limited to 100 Mbps on this frequency band. As I mentioned earlier, you should always use 5 GHz for optimal bandwidth since 2.4 GHz suffers from higher congestion, noise levels and interference.

Which ethernet NIC does your PC contain? Does the link speed indicate 1 Gbps or 100 Mbps?

[DaMan]

I don't have a dedicated adapter I use an external adapter.
actually i just checked i realized my adapter is capped at 100mb speed...

[DaMan]

how would i check what kind of connection I'm running to be sure ?

[tobiastheebe]

Which type of external adapter? It may only support 100 Mbps (Fast Ethernet).

You could execute netsh wlan show interfaces in a Command Prompt window to verify the Wi-Fi PHY link speed.

[DaMan]

It's this one :

 

[tobiastheebe]

This hub does not support gigabit ethernet.

[DaMan]

This is what i got after running the command :

[tobiastheebe]

The 144 Mbps link speed indicates a 802.11n (Wi-Fi 4) 2×2 MIMO connection, 802.11ax on 2.4 GHz may not be supported by the NIC driver or 802.11n was selected at the AP association stage due to interference/congestion. Only channel 1, 6 or 11 should be used, other (overlapping) channels should be avoided, bandwidth should be set to 2.4 GHz.

[DaMan]

Can I disable certain channels ? if so how ?

[tobiastheebe]

I doubt that modifying the 2.4 GHz radio settings will enable your Wi-Fi NIC to establish a 802.11ax connection, unless you were to specifically force 802.11ax as the PHY mode. Swapping the USB hub with a GbE-capable type or installing an internal GbE NIC are your best options. Otherwise, use 5 GHz instead of 2.4 GHz.
