Can the provider fix the signal delay between the wifi router and gadgets?

Question

Computer networks

I received such a letter from the SkyNet provider:
With the help of new systems for monitoring the quality of the wi-fi signal, we fix the signal delays between your gadgets and the router.
We want you to have a good wi-fi connection, therefore, we suggest you test the Internet with another router: if you deposit 1500 rubles to your account, we will send a technician to you and he will install a new router.
Within a week, if you do not see any changes, we will send a technician again to pick up the router, and we will return the money to your bank card.
If with a new router, everything will be better, then you can keep it for yourself.
Is this really possible or nothing more than an advertising move to sell a router?

Answer 1

There are options for how this can be done. But it's all confused ... Most likely a publicity stunt.
1. You can hack your router (see RouterScan and 3wifi). If the router has been hacked, you can ping the connected gadgets using the router.
2. Being close to the router (at the entrance), you can scan the radio channel and try to identify delays. But here you still need to determine whose specific router it is.
3. You can try to analyze all your traffic going through the provider. If you yourself ping something on the Internet, then you can try to determine the ping from the device to the router, it will only work with Windows devices, because. they send the next packet only after receiving the previous one. With linux\unix\macOS\iOS\Android, this trick will not work, their pinger does not wait for a response, but sends packets with the same frequency.
It is unlikely that your provider will be so bother. It's probably just marketing. But you do this, call them in technical support, find out someone they invented there for a new technology, for example, I became interested =)

Answer 2

It is more convenient for the provider to transfer everyone to their equipment. Then save on support.

Answer 3

Maybe. It’s just that the new router will have firmware tailored for the operator, capable of sending the necessary telemetry. And it’s also convenient for the operator to install his own device for you, which he can control, to reduce the load on technical support.

Answer 4

With the help of new wi-fi signal quality monitoring systems, we fix signal delays between your gadgets and the router.

They just want to put you a new router.
For your money
It is clear that everything is done for the money of the end user.
But this scheme is more honest. Only those who want it pay.

1. The provider can control the parameters of the client equipment (router) in various ways. The most adequate way is the TR-069 protocol, which allows the operator to monitor many parameters of subscriber equipment, as well as detect problems with the service at an early stage, and update the firmware. There are other ways to do this (snmp, manually using direct access to the equipment by name and password). But if initially access to your router is closed via TR-069 and SNMP, then no one will be able to control these parameters. More precisely, purely theoretically, it is possible to do this, but this is too "expensive" procedure and no one will bother so much.
2. As a technical representative of the operator, I can say that control over the subscriber device is very good for the subscriber himself. Why do you, as a subscriber, care about settings, connection quality, Wi-Fi channels, if the operator can do all this? If problems arise, it is enough to inform the operator and the operator will check everything himself, and perhaps even it will not be necessary to report if the operator software can itself detect problems with subscribers. All this is done solely to improve the quality and serviceability of the network.
3. About "make money by selling a new router." You yourself write that if you do not like the quality of communication, you can return the new router to the operator and get your money back. 1500 rubles is not expensive at all for a normal router. For example, the same dual-band MikroTik hAP ac² costs about 4,500 rubles.

Answer 6

Chot, no one took into account that in addition to the client router and delays in the distance between the gadget and the router, the occupied channel also affects. More precisely, the presence of other routers on this or neighboring channels (valid for apartment buildings).
And of course, yes, this is purely marketing.

Answer 7

Regardless of whether "the provider can fix the signal delay between the wifi router and gadgets" or not - this delay is the last thing that makes sense to pay attention to. So it's your brains fooling. For "1500 rubles" is not superfluous, "five old women - a ruble."
In principle, if some people have bad routers (they do not support new protocols; or the antenna chip dies) - this offer can be for them. relevant.
