Hi!
I bought a new DSL N12E ADSL Modem Router. 
I have a ZTE modem router now. I assume it is a modem router since I only have one such device from which my phone is connected to and I also have wifi. It has a DSL slot(into which I insert the phone cable) www.offshorededicated.net

When I insert the phone cable into the asus it seems to not fit. The slot is backwards so I turn the cable backwards which seems to work but I can;t tell if it;s a perfect fit since my cable switch thing(that keeps the cable from falling out is broken). But it still doesnt seem to fit and I have no idea why.

The slot on the ZTE is DSL, on ASUS- ADSL.

Will this be a problem?
