I almost bought a new router recently because the connection was so unreliable, but then I decided to at least poke around a bit. Turns out that even if reception strength is shown to be very good, there can still be other problems killing the connection.
In my case, apparently the external monitor attached to my MacBook would disturb the signal somehow. Luckily, simply switching the channel fixed it. It just never occured to me to switch the channel because signal strength was always good.
What amazed me most is that I was able to find a solution even though I had 0 idea on how to debug a WLAN network. Buying a router with a stronger signal was my only idea initally.
