Red rice note3 WiFi cutoff or suspended animation

Red rice note3 WiFi cutoff/Suspended animation

Daily use of note3, such as long time to browse the Web, click on a link will be stuck, wait more than 10 seconds before resuming. Is the first reaction a bad network? But this is often the case, compared to other phones, such as cheaper low-priced red rice 2, note3 appear too high frequency. Seriously affect the daily use, and this phenomenon is called "WiFi" or "Suspended animation."

How to prove the mobile phone "stop" "suspended animation" situation, with the simplest control test, to eliminate the bad network condition factors. In the same network situation, the same location, the same time period, with the packet test tool ping to test two phones. Compare the test statistics of two phones. It is best that you can restore two phones to the factory state.

First of all, two mobile phone automatic lock screen off, so that the phone will be lit, the two mobile phone internet other programs are closed, connected to the WiFi, open a terminal manager, keep the terminal manager's foreground running, and enter Ping x.x.x.x (x.x.x.x for router address) to start testing.

The acquisition of a large number of samples is more convincing, you can extend the test time, and finally stop the ping program, will output the test statistics results. Abort method (volume down key and C press together), some input method has pre-input box, you need to select the C output.

Well, look at my results, it's easy to reproduce, and that's not going to happen. The final statistic and explanation can be seen when the results are not understood. Low-end Red rice 2 statistical results:

---172.16.1.1 ping statistics---
288 packets transmitted, 288 received, 0% packet loss, time 287825ms
RTT Min/avg/max/mdev = 1.708/16.491/61.316/5.387 ms Red Rice note3 Statistical results:

---172.16.1.1 ping statistics---
284 packets transmitted, 284 received, 0% packet loss, time 283361ms
RTT Min/avg/max/mdev = 1.259/31.079/979.544/94.374 ms Statistical methods and explanations

Ping is a packet test gadget that can test the network's connectivity speed by sending a packet (the Internet Control Message Protocol abbreviated to ICMP) to another host, and then the host returns a packet that calculates the round trip time difference.

Each packet is sent, a packet is returned, and the time difference is output, such as this one:

Bytes from 172.16.1.1:icmp_seq=286 ttl=128 time=16.3 ms

Sent to 172.16.1.1 64 bytes of packets, round-trip time is 16.3ms, and the other icmp_seq is the ICMP queue, each sent out to add one, to the packet count. For example, icmp_seq=286 says this is the No. 286 package. The TTL is the abbreviation for time to life, and each hop is reduced by one, and becomes 0 discarded. Now just send packets to your own intranet route, ignoring the path as well.

Translate as follows:

Statistics for Ping 172.16.1.1
A total of 288 packets were sent, received a return of 288, 0% loss rate, the statistics of 287825 milliseconds,
Round trip Time (ms) min: 1.708 average: 16.491 maximum: 61.316 mean difference: 5.387 ms

The last average difference reflects the degree of data change, the greater the value, the more unstable the explanation.

Now look at the red Rice note3:

RTT Min/avg/max/mdev = 1.259/31.079/979.544/94.374 ms

Average difference reached 94! Or just a stable version of the brush, like red rice 2, red rice note3 network stability is visible, is simply unstable, can not endure.
