In July, we switched from Cogeco back to Start as our internet provider. Unlike with Cogeco, the cable modem didn't come with wireless so we had to add a wireless router. After looking on Amazon, I settled on the TP-Link Archer C50 router. I bought it in July.
What convinced me was the Amazon Editor's Choice stamp of approval and that it supported DD-WRT. I haven't installed DD-WRT on it but I will. It also doesn't hurt that it can be used as a repeater as well. And it had most of the latest standards. It has four antennae, broadcasts in either or both 2.4 GHz and 5 GHz and supports WPA 3 and b, n, g and ac standards.
I'm entirely happy with the router. All of our devices connect to it, and we have a strong signal throughout our basement apartment. That includes my wife's desktop where the signal has to go through three walls. Previously we only got 4 bars, sometimes only 3. It's only been rebooted once but that may have been the cable modem. It was easy to set up with a quick foldout sheet and a brief troubleshooting guide.
We paired it with a TP-Link wireless card as my wife was having issues with the wireless USB stick.
The configuration screen has every usual option with a couple more like guest mode and the network uses IP isolation for it by default. The router was only $39 at the time, not much more than some cheap routers that aren't as rock solid. It also came with the most recent firmware available which was released only a couple of weeks previous to my order. Maybe I was just lucky.
