Advantages and disadvantages

Advantages

No need to report the phone, the price is relatively Phone broadband is cheap

Disadvantages

Slow internet speed, frequent disconnection (one disconnection for 1-2 days, need to restart the cat in the configuration box), it will flash 2-3 times a day (It will automatically connect to about 20 seconds after the network is disconnected.)

Example of use

Newly built communities in Beijing (it should be the same in other places), the price of flyers is 4m per year for 1,000 and 10m per year for 1,200 (Now 10m cannot be opened)

4m TV network, multi-speed test software test download speed 270-300k/s, the actual download speed is generally 350-400k/s (the new community does not have a peak. )

The disconnection problem is the same as above. Those who often play online games should change to fixed-line broadband.

Price comparison of Unicom fixed-line broadband 10m per year is 1600, the difference is 400 yuan/year, so change it comfortably (At least others don’t disconnect frequently and are not affected by peaks.)

Friendly reminder

Don’t listen to what he wrote on the leaflet to enter the building 10m to the desktop (72 users in a unit, What about 1000m fiber? ), the only difference from the residential broadband is the slow network speed (the download speed of the residential broadband 4m can have 800k/s), and the peak speed is still low.
