Which is the better router in terms of reliability?

it may be the frequency strength being received by the router. I would check this first before getting a new router. this is a nuisance to have happen, especially when its the last thing you might think of. I have had it happen on several occasions.
 

FW not supported for this model. Any idea, How the router is otherwise?


Current router has no issues, it is just that it is ADSL, and now I need WAN.
