Super wifi not recognising ethernet cable

[Chart68]

I have a super wifi booster that I connect to the main router with an ethernet cable as my office is in a separate stone building to my main router. This has worked swimmingly until the weekend when we had quite a few power cuts. Ive reset both my main router & my super wifi unit but it just has an intermittent flashing light. Even if I unplug the ethernet it stil has an interrmitent flashing light. 

I know the ethernet cable is working as Ive connected it directly to my lap top.

Any ideas of what to do if I go into the broadband app it just says the booster in unavailable

Thanks

I don't know the boosters Vodafone use, but if it has a reset button I would try holding it in for 10 seconds.

Other than that it may have been damaged by the power-cuts.

Contact Vodafone, and if necessary they should replace it.

Hi Jayach

I think that is what I will be doing
