After thinking it over, I decided against the modem. Now I’m choosing between D-link DIR-300 and TP-LINK TL-WR340GD. The D-Link goes for 395 UAH, the TP-Link for 283 UAH respectively. The latter doesn’t support VPN tunnels (which, given the non-trivial setup on Linux, would have been very handy), but it does have a more powerful transmitter (which in a one-room apartment seems unnecessary anyway), and it’s cheaper. I have never been a fan of D-Link (all their equipment), but I’ll probably go with it anyway. It gets good reviews on Yandex Market.
