Troubleshoot Weird thing with an ADSL modem router

[Rawad Saeed]

Briefly explain your current issue(s)

Very slow Internet connection

Steps taken to resolve, but have been unsuccessful

Reseting the router settings
Improving WiFi password strenth
Using Mac filter

Hello.. I dunno if it's even a problem.. But I'll explain.. I've been facing a really slow Internet connection.. So I intended to check the router settings and info to see who is active and using my WiFi network.. But everything is just as it should be.. But sometimes something really weird happens.. When I insert 192.168.1.1 to go to the settings page.. I get redirected to another router settings page.. It's tells info that doesn't match my router hardware specs.. 4 ex: it tells that the router is 150mps although it's 300mps.. And doesn't take the password that I've set for access control.. .
Btw I used Mac filter to limit the devices.. And the info page shows that only the selected devices can access the network.. But I've tried wifikill Android app.. And it shows that more than 27 devices are online... So I'm very confused now

Hello

Slow internet may due to the preffered MBPS speed. What is your actual internet speed? Sometimes its a problem for your ISP.

If you will test like from Speedtest then a dramatic reduce of speed should be observe,

Does your Router use WPA2 as security? Change your Wi-Fi password, do not use the default one on router, or add an extra character (ex: * # @)

You could always reset your router and then re-enter the allowed devices.

Temporarily disable the WIFI connection and connect the cable modem to the PC.
You can see if the problem is due to unauthorized access to the WIFI network.
Useful a firmware update and the previous tips.
