Does it make sense to change the name of the network and assign a new password?

No, that doesn’t make any sense.

What are the approximate distances between the Internet box and the WLAN boxes used as radio repeaters?

@Macro09 if you want to know more about what’s going on on the WiFi frequencies you can use this app if you have an Android phone.

Of course, radio interference can occur at any time because the traffic on the WLAN bands is constantly changing.

However, you may simply have an overpopulation of WLAN boxes in too small a space and they are interfering with each other or sometimes connect to each other and no longer directly to the router.

What happens if you simply switch off the nearest WLAN-Box to the router and simply connect the TV (if it is a Swisscom TV-Box, then the TV-Box) directly to the router via WLAN?

You can redefine which box connects to which (or the router) and also which device connects to which box or router

I would optimize something here, it could very well be that the boxes don’t connect to each other in a meaningful way

In principle, it is always better if the boxes are connected directly to the router if possible, provided the reception is still good

I would also necessarily connect stationary devices to the best possible box. Devices with poor reception waste a lot of air time from the AP and therefore not only have a poor connection themselves, but also make the connection poor for all devices connected to the same WLAN radio

“Optimizing something” also includes not using a lot of Wi-Fi boxes unnecessarily - see also colleague Werner’s post above 😉

@POGO 1104 Absolutely, but that was already mentioned 🙂

@Macro09

What is also important for understanding how WLAN boxes work, which are not connected to the router as additional access points via a LAN cable, but are used purely as radio repeaters via WLAN:

The net bandwidth available to the end client is always halved because the radio repeater has to transmit in two directions at the same time on the same frequency.

WLAN boxes as repeaters are therefore not “amplifiers”, but pure relay stations to increase the maximum range while simultaneously halving the maximum net power for the end client when they are actually used.

Just as an example:

At a distance of around 6-7 meters from the Internet box, you will have a net performance of around 700 Mbit/sec with a good WLAN client.

If you now place a WLAN-Box as a relay station in between at about 3-4 meters and it is actually used by the end client, then you will have even better WLAN reception on the end client due to the shortened distance, but there will be problems at the end -Client in reality only offers 350-400 Mbit/sec due to the technical bandwidth halving.

@Macro09

And as a final remark:

In my test portfolio I have a total of 4 WLAN boxes (2 WB2 and 2 WB3) and how many of them do you think I actually use productively with a WLAN coverage area of ​​224 square meters in an apartment including terraces?

The answer is very simple: zero

In fact, with a single WLAN transmitter positioned relatively centrally, which still delivers >= 50 Mbit/sec even at the “edges” of coverage, I get the best overall performance of my entire home WLAN.

Of course, I can increase the bandwidth at the edges of my WLAN coverage area by putting additional WLAN boxes into operation, but this can only be done at the same time as accepting compromises in my main coverage area.

My personal recommendation would therefore be: only use additional WLAN boxes if the goal is to fill real WLAN coverage gaps (dark spots), and if necessary, of course, if possible, as access points on the LAN cable, because that can You can then avoid the “radio relay-related” bandwidth halving.

Have you checked all options?

You can often replace old telephone sockets or cable TV sockets with LAN sockets and wire them accordingly

@Macro09

Two lightweight walls or a reinforced concrete ceiling should normally work well, but there are more problems.

I have been using this type of installation for a long time.

Thank you for your comments.

224 m2 with just the router - I’m amazed.

How many walls does the signal pass through in your apartment and how many floors?
….

1 floor (124 sqm net in-house, gross floor plan a rectangle measuring 14 by 10 meters) divided with brick walls and window fronts to the 2 longitudinal terraces (plus a total of 100 sqm).

Maximum distance in the WLAN coverage area to the router approx. 15 meters.

Of course, every radio situation is always unique for local reasons, but assuming there are no reinforced concrete obstacles in the direct direction between the router and the WLAN client, or large water tanks, which of course reduce the range by a lot, my practical experience with maximum WLAN Ranges that still offer sufficient reception quality are approximately:

- on the faster but shorter range 5 GHz WLAN band approx. 12-14 meters

- on the slower but longer-range 2.4 GHz WLAN band approx. 18-20 meters

Since both WLAN bands run under the same SSID, each dual-band-capable WLAN client decides independently which WLAN band should be used, depending on the respective distance to the router.

Due to my local maximum distance in the WLAN coverage area of ​​approx. 15 meters (otherwise I would have to jump over the railing from the 4th floor), my mobiles almost always use the faster 5 GHz and only at the very edge of the coverage area is it used The clients themselves automatically switched to 2.4 GHz.

By the way, the trigger point for changing the WLAN band for most of my clients is around -80 to -82 dB signal strength.
