comment Moved to the 5 GHz band but my old devices don't see it
I think most 5GHz routers are dual-band routers.

comment Connect computer to external hard-drive using ethernet port
You need to configure the drive. If it's configured to get its IP address using DHCP, you need to configure a DHCP server on your machine. Having your interface configured to DHCP will only work if the drive is a DHCP server, which seems very unlikely.

comment Will I experience degraded performance on a Ethernet connection through a splitter if I'm the only user on the line?
@SnazzyE. Ahh. Then using two splitters will work, but will reduce the connections to 100Mbps. One splitter would go at the router end. The other splitter would go in either room, and then you'd need a cable from the splitter to the other room. Using a gigabit switch would work better, and they're available for around $20.

comment Pinging ip address on another interface than the one receiving the signal
@JohnyTex It makes no difference whether the routing is symmetric or asymmetric. They're treated exactly the same. My point in bringing up asymmetric routing is to make you stop thinking about the routing as symmetric as if that mattered. It happens to be true, but it also makes no difference.

comment Pinging ip address on another interface than the one receiving the signal
@JohnyTex Mainly because that was how older systems did it and because it's sometimes easier to assign and manage them that way. But for people who deal regularly with asymmetric routing and more complex setups, it can be a source of irritation, requiring IP addresses be assigned to dummy interfaces and other such annoyances. Think of it like the it in "it's raining out". The language requires you to have an "it" in order to say there's rain, but there is no thing that's actually raining.

comment Pinging ip address on another interface than the one receiving the signal
@JohnyTex If the packet's destination IP address is assigned to the machine, it shouldn't care which interface it received the packet on. Asymmetric routing is common in IP networks. As for whether you're allowed to have an IP address "on two interface at the same time", it depends precisely what you mean by "on". It's common for machines with two Ethernet interfaces to have an IP address reachable over both Ethernet interfaces.

@JohnyTex That depends on the host model. Most commonly, the IP address belongs to the computer itself.

comment Should we expect DDR3L RAM to work on the Intel first-gen Core i3 platform?
Once you know you fail a hardware test, you can omit all the details about what happens on particular operating systems. It's just noise.

comment How can I burn pictures to a CD in Windows?
You really have to ask a question when you push the Ask Question button. What's your question about burning picture files to a CD?

Why would you even try booting an OS if you're failing memtest?

I asked for clarification. The question is vague. You might be right.

Can you clarify what it is you're trying to do? Which room is your existing switch in? What are you trying to connect and where are you trying to connect it? If the line runs from your office to your bedroom and you only want one device in each room, what would you split exactly?
