Why is mobile broadband so slow? ——Hot spot analysis and solutions for the entire network in the past 10 days
Recently, mobile broadband speed issues have become a hot topic on social platforms and forums, with a large number of users complaining about network lag and high latency. This article combines the hot data of the entire network in the past 10 days to analyze the reasons and provide optimization suggestions.
1. Data statistics on hotly discussed mobile broadband issues across the Internet (June 1st - June 10th)
| platform | Amount of related topics | Maximum heat value | Main areas of complaint |
|---|---|---|---|
| 128,000 items | #mobilebroadbandstuck# 320 million reads | Guangdong, Jiangsu, Zhejiang | |
| Zhihu | 4600+ questions and answers | "What to do if mobile broadband is slow" 2.8 million views | First-tier cities account for 68% |
| Tieba | 2300+ posts | China Mobile Bar added 500 new posts in a single day | Central China and East China |
2. Distribution of main problem types reported by users
| Question type | Proportion | Typical description |
|---|---|---|
| Stuttering during evening rush hours | 42% | "The video cannot be loaded after 8pm every night" |
| High game latency | 28% | "The delay of Honor of Kings is more than 100ms all year round" |
| Web page loads slowly | 18% | "It takes 10 seconds to open the Taobao page" |
| Live buffering frequently | 12% | "Watching the live broadcast freezes every 5 minutes" |
3. Three main reasons analyzed by technical experts
1.Base station overload problem:Mobile broadband uses a shared bandwidth mechanism. Concentrated use by users from 7 to 11 o'clock in the evening will cause the load of a single base station to exceed the design capacity.
2.DNS resolution delay:Users from many places reported that the speed increased by more than 30% after switching to 114DNS or Alibaba DNS, indicating that there is room for optimization of the default DNS.
3.Line maintenance lags behind:After the epidemic, the maintenance cycle of optical fiber lines in some areas has been extended, and the proportion of old lines has increased to 17% (data from the Ministry of Industry and Information Technology in 2023).
4. Six speed-up plans that have been tested and effective
| method | Operation difficulty | expected effect |
|---|---|---|
| Modify DNS to 114.114.114.114 | ★☆☆☆☆ | Web page loading speed increased by 20-40% |
| Router sets QoS priority | ★★☆☆☆ | Game latency reduced by 30ms |
| Apply for public IP | ★★★☆☆ | P2P application speed increased by 50% |
| Replace Gigabit optical modem | ★★☆☆☆ | Broadband above 500M is necessary |
| Avoid evening rush hour downloads | ★☆☆☆☆ | Speed in the early morning can reach 3 times that of the day |
| Complaints require optimization of base stations | ★★★☆☆ | Respond within 3 working days |
5. Operators’ latest response and compensation measures
China Mobile issued an announcement through its official Weibo on June 8, acknowledging the existence of network congestion problems in some areas and launching the following solutions:
1. Accelerate the construction of 5G SA network and expect to complete coverage in key cities across the country by the end of the year
2. Provide free speed increase packages for areas where complaints are concentrated (200M users can temporarily upgrade to 500M)
3. Open a green complaint channel (dial 10086 and press 8 to go directly to the technical department)
6. Comparison of user measured data
| Before optimization | Optimization measures | After optimization | Improvement |
|---|---|---|---|
| Download speed 12MB/s | Change DNS+QoS settings | 18MB/s | 50% |
| Game delay 110ms | Apply for public IP | 68ms | 38% |
| Video buffering times 5 times/hour | Off-peak use + optical cat upgrade | 1 time/hour | 80% |
It is recommended that users choose an appropriate optimization solution based on their own circumstances. If the problem persists, they can seek rights protection through the Ministry of Industry and Information Technology’s complaint channel (12300). The mobile broadband speed problem involves multiple factors such as infrastructure and user density. It will take time to completely solve it, but the user experience can be significantly improved through reasonable optimization.
