does that make sense or is that just smoke blowing? im hard wired now with an ethernet cable directly from my ps3 into the modem. I get the ip address verified then get a dns erro and cant connect to the internet.

any advice? does that sound legit? I just wanna play Warhawk!!!! lol.

Huh that's retarded. Why becsue the DNS servers are on ISP end. If there is a DNS issue, it means that your PS3 no longer can resolve the URLs into IP addresses. Unlike PCs which have a DNS cache which can resolve addreses without contacting DNS server if that entry exits in cache. If you add a NAT based router it does nothing to DNS other than foward it to your home network devices and vice versa. Infact NAT routers (your basic internet sharing router) would make DNS issues worse in some cases Why is this an issue, well because your DNS address is the same as the router, but your router is basically fowarding the DNS requests back to your ISP and receives DNS replys from ISP and fowards them to your home network. ISPs are huge, they consist of many servers and have more than one DNS server in a given area of service. If one server is busy, the second server can take over, the ipaddress for DNS server may change, the NAT router is usually kinda slow to update the address, your network device such as PS3 will not know anything cause it uses the router's IP. Thus your PS3 can't resolve the PSN network url, your connection is interupted. You try again, and it may connect, but dissconcect at times. Trust me im MCP, A+ certified, i also use a wifi router which also has this very problem.

The tootal noob workaround would be to directly connect device to modem.

Since you are directly connected then it can be remedied with a static DNS address. First you figure out the DNS addresses, then manualy input it.

How? in the PS3 nework setting, check Network Statisitics, jot down the DNS1 and DNS2 numbers that you were given by DHCP. IPs given automatically have a lease time, then they are refreshed, an so can the DNS addresses can be refreshed. When maualy entered it forces the PS3 to only these numbers, even when your IP lease is up. This reduces the the DNS issues and not completely solve it.

thing to know: PS3 will disconect while playing PS1 or PS2 games, and DVD movies.

PSN network may have issues whith their own DNS servers which they use to host their site (DNS is required to have your own web server).
