I have two iptv providers, Both work on buzz3000 box. with and without vpn. Both wired or wifi, everything good. Now when doing the xrs4500, I gave both my prividers the address starting with 00:1A:79, one will not connect at all, and the other will not connect to portal( keeps saying cannot connect), but it will connect in the streaming line with credentials. but when trying to connect it with vpn on and its hardwired it just shuts it off, then when I unplug the ethernet and use wifi the vpn will work. and I start watching tv after 5 minutes it freezes constantly, have to change channel and go back, then works 5 minutes again. this has been constant since I got the box. tried working with my providers, even though know it cant be them because they are fine on other box. also had my internet checked by my provider. so only thing left is the xrs4500 box that has to be the issue.
