The author has two friends, living in a building, a 4 floor (hereinafter referred to as 4), a 2 floor (hereinafter referred to as 2), 4 opened broadband, home has a desktop and a notebook, 2 has a notebook, and 4 are going to share broadband Internet access. Because both have notebooks, so the use of wireless routers to share the Internet. But because of the interval between the one layer, to the 2 floor, wireless router signal is too bad, 2 fundamentally not net. Later to 2 also bought a wireless router, from 4 cloth a line to 2, through the WAN and 4 of the wireless router cascade, 2 wireless Internet access through the wireless router.
After starting router cascade configuration, the network is normal, but more than 10 days later, found that 2 can not access the Internet, and 4 regardless of wireless and wired are normal. Start to think 4 wireless router crashes, 4 of the router restart, 2 and can surf the internet, but the time is not long and there will be problems. You can't always reboot the router.
4 of wireless routers have been used for more than a year, and there have never been any problems, and 4 of the two computers were normal when 2 went wrong. The network is also normal, connecting 2 of the notebook directly from 4 to 2. 2 of the wireless router as a switch, and then the network cable to connect 2 of the notebook is no problem, is the use of wireless will have problems. With a wireless connection, you can start to ping 4 of the wireless router, but also ping the extranet such as 163.com, but after a while will be switched, until completely inaccessible.
Since 2 of the routers are newly bought, the author to find a business for a new, but after the fault is still, and find merchants borrowed a wireless router, replace 4 of the wireless router, the problem remains, and the original 4 and 2 of the wireless router have been to the merchant office, the Cascade Test but all normal. No way, had to let 2 will connect from the 4 network cable directly connected notebook use. Check a lot of data, tried n many methods, did not solve, and can be sure that the router settings and cascading settings are no problem.
You can't keep 2 of your notebooks dragging their tails. A few days later, I suddenly remembered that I was setting up a wireless router for them, the level of security involved is set very high, especially wireless encryption password, I used WPA2 encryption, password length 16, which have uppercase and lowercase letters, numbers, special characters and so on. And I was in the business test, the password only set 8, relatively simple. Will not be set the password is too complex, so that the processing load of the router caused by the network problem? Holding a try on the psychological, I put their password set to 10, the miracle appeared, when 2 of the notebook wireless internet is normal, and long time to use is no problem.
Summarize
Wireless network encryption password set a little stronger, can teach to strengthen the security of the network, if you just use a wireless router, may be a complex password is no problem, but you have to use more than two wireless router cascade, Too complex a password can cause the wireless router to load too much. Beyond its processing power. Thus causing the inability to interconnect.
