Which wireless router instead of sky ER115

We have SKY Adsl service using sky supplied ER115 router
The WiFI coverage in the Bungalow is just appaling
I plan ti disable the wifi and use an external wireless router to provide the wifi
I like the Draytek Vigor
Which model have people used with success
2830 2859 etc

Thanks in advance

Using two routers can cause issues, what you ideally want to add is a wireless access point

If your only wanting to upgrade the WiFi part and not additional features of a better router then maybe a MESH system would be better for you? There are many to choose from.
