Unfortunately iOS caching can only be done in MacOS. You can find Apple's official guide here: https://support.apple.com/guide/mac-help/set-up-content-caching-on-mac-mchl3b6c3720/mac

Yeah that is fine. When it is in router mode it sounds like a wifi issue, are you using 5Ghz? if so, make sure you are not using a DFS channel and that your wifi country is correct (to make sure the allowed bands are used and there is no interference to critical infrastructure). I took a look at an Archer C6 emulator and it looks like when I turn on AP Mode, the DHCP server is still on (this could be why the whole internet goes down). make sure that it is off and on the Network > LAN tab give your router an ip in the same range as your ISP router (use one of the last ones so that it doesn't interfere with another device. Something like 192.168.x.250) and set the Default Gateway to your ISP router's ip. The subnet mask should work at default (255.255.255.0) When you are in AP mode and the internet goes off try switching the cable from WAN to LAN (or the other way around).

I would leave the ISP router as default (make sure it is not in bridge mode and the DHCP server is on) is and setup the second router (Router A) in AP mode. You mentioned that it is a TP-Link router in AP Mode, AP mode should disable the DHCP server (that's probably why you can't see it). I have only used old TP-Link routers that don't have AP Mode and have had to do it manually but from what I've seen, it should just work. Just make sure that the connection from the ISP router is connected to the "WAN" port (it is usually yellow) ipv4 can only be automatically assigned to devices via DHCP while ipv6 is usually assigned with Router Advertisements while can also use DHCPv6 but is rarely used (at least in home setups) because Android refuses to add support for it. Take a look at the ipv6 settings on both the ISP router and on the TP-Link, the TP-Link should not be doing anything besides letting the RA or DHCPv6 work. How is this happening? that is, are your devices disconnected from the wifi, does the internet just stop working, do you get an error message?

Your lan to the global internet is the connection from the isp to your router. Whatever you get on the speed test is your bandwidth. The only things that you could to to check your router's connection to your isp are 1) check the connection link speed (10/100/1000), 2) check the latency and packet loss by pinging your router's default gateway

You only have to port forward the port used by minecraft (25565/tcp) to the the old pc. For the web server, you could keep it running on the pi and have the management page on another port (say 88 and 488). If you don't want to have the page running on another port, you could either move the web server from the pi to the old pc or setup a proxy on the pi. Web servers can identify the domain that is being accessed to change what is returned to the browser. They are usually called virtual hosts, you can find some info for nginx here

I would not recommend to connect one router to another one, you would be double NATed. The apartment router should already limit access to the local network.

are you using the vpn ip address in the traceroute or the public address? You could host a wireguard server in a vps that has good connectivity to both of you

For your case, fiber is overkill. Just run the cable either directly on the ground or in a conduit (better future proofing). Ethernet has a maximum distance of 100 meters (328 feet) so you should be fine. Because the cable is buried you don't have to worry about lightning.

share photos. Maybe we can identify it.

I also want to add that certain programs (like MInecraft) support SRV dns records. An SRV dns record gives the client an ip/hostname and a port. Allowing it to look nicer for the user. more details

You would need to run a PBX server. Crosstalk sollutions has some good videos on how to set this up. I have never set one up. If you need help, he has a discord server.

pfsense is a router os. It does not use docsis. Your modem uses docsis to convert your internet connection from coaxial cable to ethernet. pfsense just takes that ethernet connection. the issue seems to be with DHCP, the weird thing is that your computers are getting a connection but not the routers. For testing I would try to set a manual ip on pfsense. Connect the modem to your computer, write down the ip, gateway and subnet mask and set them on pfsense. This rules out the actual connection and confirms that the issue is with DHCP. I am asuming that both the AMD desktop and the HP laptop are running windows. I would tell spectrum that the direct modem (wan connection) is working on windows but not on any router.

For me cloudflare (1.1.1.1, 1.0.0.1) is the fastest but I like to use quad9 (9.9.9.9, 149.112.112.112) because It offers malware protection and the speeds stop making a difference after a certain point.

destination network should be 0.0.0.0 and gateway should be 192.168.0.1 (that's you main router's ip). but it shouldn't matter because it is not actually doing any routing. When you are connected to the second router can you access the web portal but not the internet? could you send a screenshot of ipconfig in cmd when connected to the second router Before you do that, I just looked through the settings in the simulator. Go to Security -> Basic Security and try disabling the SPI Firewall.

Bummer. I am not sure if that could be the reason why, but it is probably related. Check if your router supports OpenWRT, you might save some money
