In the DHCP setup for the wired router make sure that it is handing out a different subnet than the wireless. Also remove the gateway address. That way windows wont try to use the router as a gateway to the internet. They will only use it to talk to devices on the same subnet.

My main question would be what is currently assigning 192.168.1.x and 10.10.10.x and why not handle the routing there? Can you do what you want cheap? Sure. Go pickup a Ubiquiti ERLite-3. Configure a couple routes and you have a $100 solution. But I wouldn't call it a great solution.

Does your wireless access point at building 1 support Transparent Bridge? Often called WDS. If not your issue is likely that Wireless devices are having their MAC address rewritten by the AP. This works fine with 1 hop. Not so much with 2 hops. If it doesn't support Transparent bridge you...

It might be an issue with encrypted traffic or redirects. All google services force a redirect to the https version of the site. I'd try out some other https sites so you can rule out that variable.

More interesting from a home lab perspective is probably http://openvswitch.org/. It is a lot cheaper to spin up a bunch of virtual machines and play with how they connect to each other.

The first thing I would check is how large your DHCP range is. Make sure it is large enough to support the increased number of devices. Being an unmanaged switch means it shouldn't modify anything DHCP related. Also make sure you don't have any devices set to use a static IP inside your DHCP...

Honestly it depends on your router. With the seemingly endless accounts of consumer routers with backdoors, exploits, hardcoded passwords, and undocumented config pages it is hard to recommend allowing remote access. I'd feel more secure setting up a vpn if possible instead.

I'm slightly suspect of devices like this. I'm not sure how they can claim up to 500 Mbps when they only have a 100 Mbit/s fast ethernet port. Under ideal settings you might get 70Mbps transfer rates from them. That would be greater than your 50/10 internet. More realistically though you are...

If you have the Ubuntu desktop installed you should be able to right click the folder you want to share and select "Share this folder" or in the folder preferences there should be a tab with share settings. There should be a checkbox on if you want to allow guest sharing. If Samba isn't already...

First thing I would try would be to go to a https site. If it works. Possibly the issue is only traffic on port 80. If it works but there is a warning message there might be something trying to proxy your connection. Many home routers these days hijack dns and proxy web traffic during their...

Are the new computers and the MySQL server on the same subnet? If so we can rule out the router. Can the new computers ping the MySQL server or access any other functions of it? Trying to rule out if it is solely a MySQL issue. Possibly authentication related. Can you ping the MySQL server...

Most modems have more than 1 port. Just hook the backup to that. If it doesn't you are going to need to add a switch connecting routers and modem. Follow this guide to setup the firewalls. You don't want them completely identical. They each need their own LAN IP. They will share a virtual IP...

You may get substantial crosstalk in the wires if you don't follow the 568a or 568b standards. They came about for a reason.

If the laptop and router aren't connected to anything else what is at 192.168.0.10? DMZ in a router like that just means it is going to forward any request made to 192.168.1.15 to 192.168.0.10. So say you had a webpage hosted on port 8080 of 192.168.0.10. If you went to http://192.168.1.15:8080...

Just remember if your WLAN and LAN are separate subnets and you don't set a gateway on the NAS it needs to have an interface on both subnets. Though personally I would probably still go the firewall approach as no default gateway is also going to break VPN access to it. But that is mostly...
