i have a Dell dimension 4550 Pc Win XP with both an ethernet connection and wireles adaptor connection to my new router. Everything worked fine for first 3 weeks. Last friday i carried out a disk clean up, defragmentation and deleted old music and video files and added a second 256mb ram. I now have no internet connection from my pc. Other computers, iphones etc can still access my wireless internet connection and through a cable connection. On my pc under network connections it shows i am connected to the router, this is when i input the Ip address and DNS numbers myself, under (TPI/IP)properties. However if i let the computer select automatically i get no connection to the router. i.e. the static DNS number gives me a router connection, i think! My internet provider says i have to let it automatically select the IP and DNS numebrs however it does connect. The router is new from Perlico/Ireland and is called ZyEXL? I have turned off security updates and the firewall on the pc. CMD/ipconfig shows up the IP address i have put in, however if i ping a website, the host server can not be contacted. i believe the router might be ok as it works with other pcs, the problem is might be afile missing on my pc?? i thought I was careful not to delete anything other than music files etc, so i do not understand what is wrong, i ahev spent an hour on the phone to the internet provider to no avail. my LAN card on the pc is working. i have reset the router a few times also. and under internet, tools options/connections i have never dial a connection ticked. any thoughts or advise would be appreciated, thanks

Post the results of ipconfig/all command. Silence is golden but duct tape is silver

Hi i have put ipconfig /all through and all is fine, ie 4 replies and o files lost etc. I ran ipconfig /renew and an error occured with a operation requiring a socket. apologies but i do not the pc in front for me at the moment to qoute exactly. I deleted the security software (add/remove programmes) as provided by my internet provider, it is called F Secure. I believe the error...socket means i still have a firewall up and running, even though i have it disabled. I found an internet provider security folder in the system files and tried to delete all the files in there however some .dll files are still running and will not delete, i have rebooted the pc a few times and they still will not delete. i believe they are running a firewall that is preventing me from accessing the internet, does that make sense? any suggestions from there? i would prefer not to wipe my pc to factory settings, no idea where the disks are. i appreciate you're interest, any suggestions welcomed. thanks roy
