cmcc initial wifi should be 8 8 or 8 0. At present basically every domestic family will have their own home Wifi, and in order to "prevent rubbing the net", they also designed a number of passwords. Recently, a domestic organization used big data statistics to come up with the top ten common home Wifi passwords for Chinese families, come and see if there is a password for your home. The list shows that the top three passwords are 12345678, 123456789 and 8888888888. the total percentage of these three passwords is 7.437%. Don't underestimate this 7.437%, in fact, this has been recognized by cyber security experts as a very scary percentage. This is because in the case of a malicious hacker attack, the probability of them breaking through this password protection is over 80.1%. (Actually, personally, I feel that you can break a password like this by finding me in the past, so why bother with the hackers.) Moving on, the list of top 10 common home Wifi passwords covers 10.355% of all Wifi password samples, which means that if you search for ten Wifi signals at the same time, there's at least one of them that you can connect to with the above password. So again, we see that the home Wifi security situation in China is still very serious. In fact, if a hacker intentionally attacks your Wifi router and plants a Trojan horse, almost everything we do on the mobile side is **** being monitored. Including our chat records, financial transaction records, etc. may be stolen. Some routers don't have a password initially. CMCC has two meanings, one refers to China Mobile Corporation, and the other refers to a wireless broadband access service provided by China Mobile.
