LAN no internet access -when connecting to PS3 with ethernet cable

[sach]

hey

hoping someone can help me out

I'm a 3g dongle to connect to the net, I previously set up the ps3 to connect through same via the wired connection.
That work fine for a bit, until I updated the firmware, Since then the PS can't seem to obtain an IP address and after setting a static IP it gives me a DNS error. On the flip side, my LAN is giving me a no internet access problem(ipv4) and also an unidentified network

I've changed the cable, released and renewed and reset the ipconfig and also flush DNS. I'm having the same problem with my laptop. Both were able to share the connection with the PS3 before.

(Pc runs windows 7 32 bit and laptop win 7 64bit)

Any suggestions?

By LAN do you mean your network icon on the PC your dongle's connected to? I assume you're using a router right? This may be an insultingly simple tip, but did you power cycle that router yet?

no I am using a usb modem, not using a router, sharing internet via the ethernet port.
