Hi, No reply from experts of this forum

Have you reset your router to factory defaults and then run a Wi-Fi Inspector scan?

Hi, what would that tell in wifi inspector. You just want me to reset and then scan. I will not get internet connection , if i do not reconfigirue then?
Will you please tell me what those vk.com and yandex.ru. are these stored in my computer?

Reset the router and run the scan again.
Let us know what the scan says after the reset.

Hi, Eddy and Ali sorry in delay in replying,
i have taken two scan analysis and they are produced below. One, in factory reset status of router, where no internet connection was available. It just gives you weak password alert
Secondly, after configuration, to get my internet access, i scanned again and the same is reproduced below
Now i do not have alert of hns hijack symptons. pl note
there is no mention of vk.com and yandex.ru, as before.
Would you please say, what are those sites sitting on my computer router, or in computer. what is called hijacked domain. I do not have any domain myself. I am a normal user of internet.

Hi, can i expect a reply for this query. why some queries are just passed without answer?
