We had weak wifi signal through out the house and I got a Dlink router to help, on one of the desktops that's used for games, we experience constant drop in the internet connection, wifi connected-No Internet, this may happen to other devices too but this one is noticeable and quite frequent. Does Wireshark have any tool to help find out how many times the internet connection drops and for what IP addresses? That's all I need! thank you.

You probably have to login into your router or WIFI Access Point and look for error messsages.

If you want to use Wireshark to investigate you'll needs to capture the traffic at the WAN side of the router. How this can be done depends on your equipment. (For example, I have FttH and can use a managend switch to capture WAN traffic via a monitor port.)

However, you also mention it is used for gaming. In that case I recommend using a LAN-cable instead (and a gigabit switch). WIFI adds a significant latency to your connections, which is bad for online gaming.

Thanks for the reply, I bought this D-Link AC2200 that comes with 2 access points, bridged my Shaw modem, put one of the access points on my son's desk where he plays games so he'll get more signal because he's far from the main router, I tried both wifi and wired connection from his desktop to this access point but the internet keeps dropping, he turned off the access point and connected to the router itself last night, we'll see if that makes any difference. Unfortunately I can't run a long cable from the router/modem to his room, so wifi is the only option. I'm in the same room as the router and remote to my work desktop all day, I'm not disconnected from the internet through out the day so it seems the issue is the distance from the router!

Maybe a Powerline Adapter is better in this case. The benefit of a wired connection without a 'long cable'.

So the Access Point (AP) is close to the desktop, that explains why it reports WIFI connected. But the signal between AP and router can still be an issue. Walls, floors, glass, metal, etc. will reduce the signal strength and microwaves, DECT phones, neighbour's WIFI can also interfere.

I have one of those, currently using for the basement smart TV. This D-Link COVR router came with two additional wireless access points, but apparently they are the problem themselves!

I don't think it is the right tool for you. I honestly wouldn't know what would be a good tool for you in this case.

Yeah it's a simple task when you're troubleshooting your internet connection, I hope there's such tool. I can get the router log, don't know what I should look for in the file!
