Router/DNS probs. 

Depending on how the routers pass packets around, the way many shared building ISPs work is to block on TTLs on packets. They set TTLs to minimum so every router affects the TTL enough to reject at their perimeter. 

We have found several ways round this but the better ones get a bit techie and require you to run your own DHCP and DNS or have complete control over the Routers with a linux router image. 

Other than that really depends on how you have the LAN structured. Often, using cable or powerplugs to link the old routers as wifi repeaters can help, or using them as wifi only repeaters but anything that produces an overhead may hit the TTL and result in packet rejection.
