Correct, the Vodafone supplied router is known for random/frequent disconnections, causing DLM to mess up your FTTC line profile.
I would stay away from Zyxel routers as the wifi on them is nothing special and they're not cheap either.
If you want the crème de la crème of DSL routers with a solid xDSL chipset and excellent wifi then one of the Netgear D7800, TP Link VR2800, Billion 8900AX-2400 or Asus DSL-AC88U will be an excellent choice. Personally I would go for the Billion out of those.
If the above are out of your price range then something like the TP Link VR900v2, TP Link VR600, Netgear D6400 or Billion 8800NL are good cheaper alternatives but not as good as the above.
