Everything works fine now. The problem was with Mcafee firewall.
Hello, I have a Dell Inspirion N5110. Recently I have been unable to connect to the internet through a router (both wireless and using a wire). I can use the internet if I connect the laptop directly to the modem. The laptop successfully connects to the wireless network, and other devices on this network can access the internet. I ran ipconfig /all and these are the results: I use the Wireless LAN adapter Wireless Network Connection Windows IP Configuration   Host Name . . . . . . . . . . . . : Yael-PC   Primary Dns Suffix  . . . . . . . :    Node Type . . . . . . . . . . . . : Hybrid   IP Routing Enabled. . . . . . . . : No   WINS Proxy Enabled. . . . . . . . : NoWireless LAN adapter Wireless Network Connection 3:   Media State . . . . . . . . . . . : Media disconnected   Connection-specific DNS Suffix  . :    Description . . . . . . . . . . . : Microsoft Virtual WiFi Miniport Adapter #2   Physical Address. . . . . . . . . : BC-77-37-2F-ED-11   DHCP Enabled. . . . . . . . . . . : Yes   Autoconfiguration Enabled . . . . : YesWireless LAN adapter Wireless Network Connection 2:   Media State . . . . . . . . . . . : Media disconnected   Connection-specific DNS Suffix  . :    Description . . . . . . . . . . . : Microsoft Virtual WiFi Miniport Adapter   Physical Address. . . . . . . . . : BC-77-37-2F-ED-11   DHCP Enabled. . . . . . . . . . . : Yes   Autoconfiguration Enabled . . . . : YesWireless LAN adapter Wireless Network Connection:   Connection-specific DNS Suffix  . :    Description . . . . . . . . . . . : Intel(R) Centrino(R) Wireless-N 1030   Physical Address. . . . . . . . . : BC-77-37-2F-ED-10   DHCP Enabled. . . . . . . . . . . : Yes   Autoconfiguration Enabled . . . . : Yes   Link-local IPv6 Address . . . . . : fe80::14bf:f30e:d0bd:1100%14(Preferred)    IPv4 Address. . . . . . . . . . . : 192.168.1.103(Preferred)    Subnet Mask . . . . . . . . . . . : 255.255.255.0   Lease Obtained. . . . . . . . . . : ‰…˜€™… 26 €‰ 2013 19:58:32   Lease Expires . . . . . . . . . . : ‰…˜€™… 26 €‰ 2013 21:58:28   Default Gateway . . . . . . . . . : 192.168.1.1   DHCP Server . . . . . . . . . . . : 192.168.1.1   DHCPv6 IAID . . . . . . . . . . . : 381450039   DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-15-25-C0-21-78-2B-CB-E0-F5-44   DNS Servers . . . . . . . . . . . : 212.143.212.143                                       194.90.1.5   NetBIOS over Tcpip. . . . . . . . : EnabledEthernet adapter Local Area Connection:   Media State . . . . . . . . . . . : Media disconnected   Connection-specific DNS Suffix  . :    Description . . . . . . . . . . . : Realtek PCIe FE Family Controller   Physical Address. . . . . . . . . : 78-2B-CB-E0-F5-44   DHCP Enabled. . . . . . . . . . . : Yes   Autoconfiguration Enabled . . . . : YesEthernet adapter Bluetooth Network Connection:   Media State . . . . . . . . . . . : Media disconnected   Connection-specific DNS Suffix  . :    Description . . . . . . . . . . . : Bluetooth Device (Personal Area Network)   Physical Address. . . . . . . . . : BC-77-37-2F-ED-14   DHCP Enabled. . . . . . . . . . . : Yes   Autoconfiguration Enabled . . . . : YesTunnel adapter isatap.{2788B516-F750-430E-A874-79D3503167F6}:   Media State . . . . . . . . . . . : Media disconnected   Connection-specific DNS Suffix  . :    Description . . . . . . . . . . . : Microsoft ISATAP Adapter #2   Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0   DHCP Enabled. . . . . . . . . . . : No   Autoconfiguration Enabled . . . . : YesTunnel adapter Local Area Connection* 20:   Connection-specific DNS Suffix  . :    Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface   Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0   DHCP Enabled. . . . . . . . . . . : No   Autoconfiguration Enabled . . . . : Yes   IPv6 Address. . . . . . . . . . . : 2001:0:9d38:953c:2c86:b0be:aabf:dce1(Preferred)    Link-local IPv6 Address . . . . . : fe80::2c86:b0be:aabf:dce1%27(Preferred)    Default Gateway . . . . . . . . . : ::   NetBIOS over Tcpip. . . . . . . . : Disabled Please help me :emotion-11:
