1, the latest boot 1-2 computer can even not on the network, web pages and qq all not line, network access to a Shared works,
2, if the boot around 9:00 broken network, don't do any operation, about 11 points to 12 points between network will automatically return to normal, the ping command has been found monitoring,
3, before the Internet back to normal, replace the IP address manually, or automatically obtain IP address, the ping command (ping the domain name or IP address) have shown "request timeout,"
4, accidental discovery, also can appear offline in the afternoon, change the IP address manually, ping displays the request timeout, but offline time is shorter, about half an hour automatic back to normal,
5, the cycle, the next day and repeat the above problems,
Temporary solution:
1, every day early to boot your computer, manually set the IP address, test (for example, manually 192.168.0.10, ping command TongWai network measurement to 0.11 after continue to test, test again after change new, about 10 IP address)
2, when the other computer broken network condition, manually change the IP address for testing in advance 192.168.0.10, the computer can normal Internet access,
The network environment:
1, the network device has pix525 firewall, router, switch, wireless AP, huawei small dlink wireless router
2, the network Settings: equipped with LAN, domain control server for DHCP and DNS roles
3, wireless AP and wireless routing are fixed IP, struck a different segment vlan (192.168.3. X)
Analysis concluded that:
1, broken network fault is, after adding huawei wireless AP and AP?
But please huawei official remote login, configuration problem was found, and the broken one night AC, the AP power, the second day still appear offline,
2, about 2 hours without Internet, where is the cache aging or 2 hours is the lease?
3, a new discovery: 10 test IP address at ordinary times, about 1-2 off computer network; Tested 20 IP address today, there are five or six computer broken network, and networked computer quantity about?
Sincerely ask bosses give directions!

When offline, arp -a read the MAC address of gateway, ping gateway can see through? Couldn't get on the net is generally related to the gateway or gateway MAC lost, or someone pretending to be gateway, or the gateway no response?
