I’ve been doing computer work for over 15 years professionally and over 20 years personally Bc my mom did coding in the 80# for her job so I got started before all the people my age even had comps (im 34). I previously working for Comcast as an internet tech over the phone. I worked for them before they sent a lot of the support overseas and apparently quit putting money into their own employees training what reps are here.. my experience is 3 years with Comcast IP tech support tier 1 and 2, also a lead of an advanced resolution team. I’ve read all the comments above and before you change stuff I’m curious about a couple of things.. do you have packet loss and have you performed a trace Route? Besides your standard cable stuff and your neighbors, do you have any one in your area that you know of that has any external antennas or anything like that? They would likely be very old. Do your neighbors have any issues with their service? There is a lot of outside interference that can contribute to your problems unfortunately. I hate assuming but I am going to assume Comcast has come out, replaced your drop(line from the tap, green box or up on the power line, to the outside connection on your home), inside and outside wiring and modem/router. While the person mentioning about the WiFi channels is correct as far as that is concerned if you are having problems with other services of Comcast (phone and tv)? Do you? i do heavily agree with purchasing your own equipment. You can actually purchase an eMTA for your phone and a separate modem and separate router. If you choose to get separate modem and router, do not place them right next to each other or on top of each other. I recommend getting a short Ethernet cable and about a foot apart. They can interfere with each other. If you are using the standard modem band of 2.4ghz, I recommend any cordless phones be unplugged if not in use and any other items that use 2.4ghz. If your device has the option, always use 5ghz if you can. Ill hopefully be able to help. I hate the way Comcast customers want to make customers pay for service but doesn’t want to fix th problem when it’s down. Their techs are lazy most of the time or again they are outsourced contractors.

Can you find a maker space with a CNC router? That's probably how these were made, and the easiest way to do this. Other than that you'd want to make a template for the router to follow, and use a collar on the router to follow the template, The round holes I'd do on a drill press. Making the template will be a fair amount of work. I'd drill the ends of the elongaed holes on the drill press than use a jigsaw to cut the straight sides, finishing up with files and rasps to get them straight. They'll need to be oversize of your final holes by the difference between your router bit and collar diameters. Doable? Yes, certainly. Easy? Not so much. Piece of cake with a CNC router. Watch some youtube videos on template routing. The good news is that once you make the template you can make dozens of the final product.

How much do you need? If it's a lot then look for a router bit with a matching profile or, worst case, make a knife for a shaper insert cutter. If you only need a few feet I'd cut a square rabbet on the corner with either a router or table saw then round off the corners by hand with a spokeshave, small plane, or even sandpaper.

If each of the Nighthawk's 4 Lan sockets will enable your VOIP system, and if the same cord doesn't activate a connection for the PC, I would suspect the PC to be the problem. Two possible solutions, the second only if the first doesn't work #1, go to Settings, Network and Internet, Ethernet, Change Adapter Options, Right Click on the Ethernet adapter icon and make sure it's enabled. If it IS enabled, your option after right clicking will be to Disable. If it's enabled and it doesn't connect, move on to #2. #2 - if it is enabled but won't automatically make the connection, you should consider buying a USB Wifi adaptor. Don't go for the cheapest ones but for $20-$30, you'll have a little device that mostly installs itself and will work well. I bought this one when I decided to press into service in a distant location an older PC I'd stopped using. It doesn't have a built in Wifi capability. With this little device that I have plugged in at the back so it's really not visible, it connects at the same max speed that much newer devices can connect at, on both wifi bands. USB Wifi adapter
