Is this a hardware issue or router issue?

I don't know what is going on. Ever since we switched from the Xfinity modem to 3 different custom rouer modems, my packets were constantly being loss. However, my brother's laptop was fine with these custom router modems. After 3 different devices, we settled on the C7000v2. Like before, I constantly lag while my brother is doing just fine. I thought it was a hardware issue but we went back to the Xfinity modem today and my connection won't drop and I don't loose packets anymore. What is going on? I really want to use the C7000v2 but it seems like anything that isn't a Xfinity router or modem just won't work for me. Do you guys know any settings that could stablize the packet loss on the C7000v2 login? Could you send me a screen shot of your settings? Also, is it bad to use the C7000v2 since it is a modem router combo? Should I just buy a modem and buy a router? If so, what would a good combo be that is below 300 dollars.

    The c7000v2 is a docsis 3.0 device. You don't put what the xfinity modem model is. If it was a docsis 3.1 device, it might have been a little more tolerant of signal issues. You don't include any logs or signal info either. 
    I'd log into the c7000v2's connections page and logs page. Take a screen snip of both (get all the info) and post it back here. It can help determine if your line is borderline. If the signals sketchy but not fully bad, it might have been why the xfinity model tolerated it better.

        The main page of the browser admin page has "connections". click on it. 

        for the logs go to ADVANCED > Administration > Logs.

    • Also, how does this explain that I have issues while my brother doesn't? He is actually further from the router than I am too.

        Well we first have to determine if its a modem issue or a router issue. 

        You didn't put much info on your post about your computer or his but maybe his computer has a better wifi card in it. 

        Or maybe your wifi card has issues that respond better to certain wifi chipsets. 

        and without knowing the xfinity model you're using, we don't have much info. maybe the xfinity one has band steering and is placing you on a better channel. the C7000v2 doesn't have band steering. 

        what wifi card are you using?

        have you tried changing wireless channels? 

         

        its tough to troubleshoot with vague information.
