Can't connect to certain websites on wifi repeater

[Apostolis_1]

Hi! I have connected a wifi repeater to a wifi repeater to a router... I know it's weird but the range of both the devices is short and I tried extending the range like that!
The problem is that some websites don't load with the error err_name_not_resolved... Tried Firefox too no luck!
When connected to the router or the first repeater (the one connected to the router) there is no problem! When connected to the second repeater (the one connected to the first repeater) the problems begin!
How can I solve that?

it's only a weak signal nothing with your repeater

No I tried it with all three devices near me. Facebook works for example... Ebay doesn't on the other hand..!

could it be a DNS issue on your router ?

The thing is that when connected to the router itself or the repeater that is directly connected to the router, I have no issues... And I've tried with both repeaters all combinations

That's a DNS error. For whatever reason, your DNS queries (translating domain names into IP addresses) aren't able to traverse your second repeater or are taking too long.

DNS errors can be a bit deceptive because prior DNS queries are cached on your computer. That may be why Facebook is working but eBay isn't. Facebook's DNS may be cached. Connect to the second repeater, open up a command prompt and type:

ipconfig /flushdns

That will clear out the cache. Then see if some sites work, some don't. I'm betting they'll all stop working.
