Why are there different values for broadband measurements on different devices?

Background:

We have a VDSL connection with 100 Mbit / s. This week we were made aware by the Telekom that our previous Speedport W 723V can't cover our connection, which means that it was changed yesterday by the Speedport Smart. Now, out of interest, I have carried out the following measurements through breitbandmess.de.

Measurements:

PC (measurement by Fritz WLAN stick of older generation):

Download 47.88 Mbit / s
Upload 23.81 Mbit / s

Laptop:

Download 49.94 Mbit / s
Upload 30.82 Mbit / s

Samsung Galaxy A5 (6):

Download 53.33 Mbit / s
Upload 33.45 Mbit / s

IPad 2019:

Download 103.02 Mbit / s
Upload 33.13 Mbit / s

Notes on measurement:

The measurements were all carried out in sequence between 7:15 a.m. And 7:30 a.m. During the measurement on one device, the other devices were always off or not connected to the WLAN. All measurements were carried out via WLAN and all from the same location of the device. Only the WLAN with 2.4 GHz is active at the Speedport.

How can it be that all four devices have different values, especially the download value of the iPad 2019?

This is simply because the iPad has the better antenna.

Because the built-in receivers are different.

Which receiver can I use for my PC to get values as good as the IPad?

As the others have already written, this is simply due to the built-in WLAN module of the end devices. The values would also be different via the 5Ghz WLAN. But you could definitely operate the more modern devices in the 5Ghz WLAN and the older ones that do not support it over 2.4 Ghz. It is then important to configure both WLANs differently in the router. (Name, Wi-Fi channel etc.)

To really get the most out of your line, especially on a PC / laptop, you should use fixed cabling, i.e. RJ45 LAN. Depending on the living situation and structural conditions, this is of course difficult. But this way you could reach the speed that arrives at your router.

One with WLAN 802.11n or .11ac

Could you recommend me a specific WLAN stick that supports both 2.4 GHz and 5 GHz and is of good quality. I have absolutely no idea about this.

Thank you for your response. Is there a manual or an explanatory video at igrendwo showing how to activate and name the 5 GHz WLAN?

In the case I decide against a LAN connection on the PC, which WLAN stick could I get almost as good values as with the iPad 2019?

We do not offer WLAN sticks directly, so I can't recommend anything from experience. I would always prefer the cable if possible.

Instructions on how to optimize Wi-Fi at home can be found e.g. On our homepage: https://www.telekom.de/...ecked=true

Our MeinMagenta app also has this function.

You are right that a LAN cable would of course be the best variant, but it is difficult for me to lay the cable, since I can't arbitrarily drill holes through the walls, but only use those that already exist. That would mean that the cable would have to be quite long, since it literally has to be placed over 7 corners and thus has to be about four times as long as the WLAN stick is today from the router. Because of this, I have never used a LAN cable.

The main problem is the Wi-Fi. Encryption and decryption take time, only one can send and data can only be transmitted in one direction.

The longer the encryption or decryption takes, the more pause after receipt before a new data packet is requested. The more modern the chips in the WLAN module of the stick or card, the smaller the pauses (latency) and the more net data you get.

The iPad works very differently, here the encryption is integrated in the operating system, so it runs via the very strong main processor instead of the small microcontroller on a USB stick. The iPad also uses a few tricks to be faster, but this is at the expense of other participants in the radio network. It's like pushing through a queue, not fine but very effective for yourself.

The best thing is still cable, because you get the highest data rates through the router and have advantages with online games, you always play with WLAN in the past, so to speak.
