    Hello, as I do not have access to my router because it is in the so-called the lease of any changes is made remotely by the internet service provider. Using the wifi analyzer (android) and inSSIDer (PC) applications, I have set channel 6 + 2. I asked the service provider to change the channel to 13. Confirmed the change to the indicated channel 13 but in both applications for checking wifi there is still a 6 + 2 channel. The Android app suggests the best 9 + 13 channels; 13 + 9; 8 + 12. What's the deal with these channels, i.e. what is the difference between channel 13 and 13 + 9? Has the service provider set channel 13 and the programs show 6 + 2.

    And what is a 6 + 2 channel ???
    What application and how does it suggest?

    I wrote it in the first post. I have the WiFi Analyzer application on my phone, and inSSIDer 2.0 on the PC and on both shows that my router is broadcasting on the 6 + 2 channel

    The application on the WiFi Analyzer phone suggests better channels 9 + 13, 13 + 9 and also shows that I have set channel 6 + 2.

    I also use WiFiAnalizer and I did not find it in it: 6 + 2 ???
    The WiFi band is so narrow that the chances of getting an uninterrupted signal in the 2.4 GHz band are zero. There are 13 channels every 5MHz, and each "polite" because they are rude, the router takes a minimum of 20 MHz, or four (!) Channels. If you want to use the full speed of n'ki then we occupy 40MHz or eight (!) Channels from thirteen! And, as a rule, our router is not alone in the ether ...
    That's why a lot of people go to 5GHz but there is more attenuation and DFS ... It's tight and that's it, and people have requirements like the link type 300Mb ... and here ... a button with a pendant.

    Well, the chart shows that my router takes 8 channels (0-8) and works on channel 6 + 2. The thirteenth channel is definitely not set.

    Some Users, when using the Wizard when setting up their TP-Link for the first time, set / select a specific channel and channel width to 40Mhz, hence the spectrum of eight channels occupied. The 6 + 2 notation indicates that the main channel is channel 6, which is expanded by the scope of channel 2.

    Thanks, though I guessed earlier. Strange notation, but there is a sure method. In routers we have HT40 and +, -. which is the second channel higher or lower than the main one.
    The 6 + 2 notation indicates that the main channel is 6, the second is 2, i.e. below.

    So the service provider did not change this channel as I asked. Or changed instead of saving new settings. I need to contact you again regarding this matter.

    I do not know about you, but I would not bear the situation that someone pokes remotely in the router at my house. Isn't it better to spend a little money and free yourself from this serfdom?
    Even for your own security and privacy. After all, the provider has access to your home network and greater authority in its management than you ... Maybe for some it is convenient, but my skin suffers

    Have you restarted the router?

    I agree with you 100%, but in my city there is one specific company that has a monopoly on optical fiber and has a decent offer. The downside is that they share their equipment with seals and passwords. Of course I could go to some local radio, but this is padaka, expensive for low transfers.

    PS how to check the IP address of the router to which the service provider remotely connects. Maybe I could connect and change the data myself.

    I have a 5GHz radio. When they set it up for me, I already had my router and wanted it to stick only for stupid AP. I did not agree to this and connected the cable to the WAN and not to the LAN of my router. They shook their nose, but I have control over the home network at the expense of another NAT that slows down the transmission. In my case it is not a problem because I have only 8 Mb. With an optical fiber, e.g. 80 Mb, you must have a very efficient router in order not to experience a slowdown in transfer.
    What router do you have from the supplier? Give photos of connections.

    the router is Dasan 640GW, the connected optical fiber and visible seal, the network cable is Internet TV.

    In wide-area optical fiber networks, individual routers are no longer used because they cannot be managed. GPON ONT terminals are used:
    https://pl.wikipedia.org/wiki/Gigabitowa_Pasywna_Sie%C4%87_Optyczna
    This solution allows central management (configuration, software update, etc.) of hundreds or thousands of devices from one place. They are managed from the WAN side, i.e. fiber optics, and each terminal must be configured to match the rest of the network. Such times, such technologies ...

    Approx. I understand that this is convenient for the supplier. With the user, especially the more demanding, read annoying, it is worse. For me, the situation described by the author is unacceptable.
    The question is whether the provider will agree to reconfigure this terminal to connect its router. Is it about connecting the router to the LAN port of the terminal and turning off WiFi?
    I am asking on behalf of the author of the subject, and in a way my own, because there are plans to "hang" the fiber in my area.

    Connecting a second router and turning off wifi in the first one is possible, the provider sees no problem connecting me to his router and he will turn off wifi on his. It just doesn't suit me, because after all, it's two devices already.

    Everyone does as he thinks, is more comfortable for him, values something more, etc.
    For me it is unacceptable and you go your way.
    Good luck.
    Ps thank you for the lesson. Thanks to your topic I gained some important knowledge.
    Pzdr.

    And I'm wondering if the supplier will make him connect his router as AP or will put his equipment in bridge mode because that is also a big difference.

    In general, I was able to remove login details on the router and all I do is at my own risk. I stayed at the service provider's router.
