As a German who lived a prolonged time abroad, I might have a perspective. I wasn't actually aware that I would be forced to use Fritz products here, but they certainly seem omnipresent. My 7530AX performs actually flawless, no complaints there. I wished it would offer more functionality, e.g. NFS, ability to force some clients to use either 2.4 or 5GHz (to circumvent a current bug in the Nokia G20) or make it easier to upload Linux on them, but I wouldn't call it a bad product. I'd rather give it 4 out of 5 stars. I liked my Linksys WRT54GL, but that was very dated (too slow to exploit the 50Mbps connection to the Internet and no 5GHz) when I finally left it behind during the last move. The Dlink product (713p?) I used (much) earlier was poor, with buggy firmware not supported or maintained by the manufacturer after sale.
Dropping Internet connections which are fixed by a restart sounds to me like a marginal connection (the restart forces a re-learn of DSL parameters). The Fritz box should be able to diagnose that.
