Working as a technician in a black Internet cafe

For various reasons, I found a technician's errand in the Internet cafe .... It's not easy to say tired or tired... After all, the black bars are black bars. The network speed is slow, the machines are poor, and the management is not in place. Those guests still complain about this ..... Ah

Network engineering is indeed complicated... Two 2 m networks constitute a simple lan, dual-WAN router, Gigabit Switch, 16 with no disk in the navigation tray, and 4 with disks...

Recently, the Network is always disconnected, and no reason can be found at all... The network cable, vro, vswitch, and network card are optimized ....

The guests are still complaining... Helpless, angry ~~

Then I thought of the underlying layer... I got a speed limiter on the Internet. Although the network is better, I felt uncomfortable, so I wrote it myself .. Very proud ....

Due to the problem of sometimes getting stuck, the External Department can re-detect the external line .... As a result, a telephone line fault was found... 1 cat to 2 router, but also to save 1 yuan .... --... We should all know later ........... Tested by the tester and laptop...
