Hello, there is a Netis MW5230 router, as well as a modem that is inserted into the zte router (with the Vodafone logo) MF833V in which there is a Kyivstar SIM card, the modem is connected to an external antenna, operates in 4g only mode. It worked well, but problems started a week ago (at this time, the settings did not change, the devices were not manipulated). Everything works fine and then the pages stop loading (in chrome err_connection_refused).
It happens that off / on Wi-Fi on a laptop and the site is loaded again, and the next ones are gone (unless it takes a long time to reload and something will load), but the one that loaded works fine, you can navigate through the pages.
To catch what the problem is, in a router or modem, I connected the modem to the computer, and from the computer I distributed it via an Ethernet cable to the router (it turned out: Internet from the modem - computer - router - phone, laptop via Wi-Fi (according to this instruction)). Began to wait for problems. Sites from the laptop stopped loading normally, the computer does not load normally (the problem is in the modem), but it works on the phone (!), YouTube loads, although it does not on the laptop and computer. After reconnecting the modem, everything began to work again.
Tell me what the problem is, I understood it myself as best I could, but I don't understand what the problem is, can the modem be reflashed?
Answer
Hello. When you set up this scheme (modem + laptop + router) and the Internet disappeared on the laptop and PC, and worked on the phone, then the mobile Internet could work on the phone. When Wi-Fi is without internet access, the phone can use cellular data. The fact that the Internet disappeared on a laptop is enough.
Well, it's not entirely clear whether the Internet disappears on all devices when connected through a router? When the ZTE MF833V modem is connected directly to the Netis MW5230 and the router distributes the Internet to all devices. Well, it's not clear with the reboot. Does the Internet start working after restarting a router or laptop? If the laptop (and disappears only on the laptop), then everything is in order with the modem / operator / router.
But I think, all the same, the operator breaks the connection for some reason. Perhaps due to overloaded base stations (now there is a heavy load at the time of quarantine). I would try in the modem / router settings to set the mixed mode of 3G / 4G operation. Or just 3G. For verification, at least.
You can also try on a laptop, in the connection properties (Wi-Fi network), register DNS according to this instruction.
