In this article, we will analyze all possible causes of low speed and offer 10 proven solutions that will help restore the Redmi Note 7 to its former speed on the network.
It is important to understand that the speed of the Internet depends on many factors: from the load of the operatorβs base station to the firmware settings. MIUI. We're not going to suggest magic buttons, but we're going to focus on technical methods that actually work, and if you have all the tips, if you have the problem, it's probably the hardware constraints of the model or the external conditions (e.g., a weak signal). 4G in your region).
So let's start with the simpler ways, and we'll gradually move to more complex settings. Most methods don't require root rights, but some require access to an engineering menu. All instructions are tailored specifically for the Redmi Note. 7 (codename lavender) and checked on current versions MIUI 12-14.
1. Checking the current speed and diagnosing problems
Before optimizing, you need to understand where exactly your Internet is slowing down. MIUI.
The easiest way to check the speed through online services:
- π Speedtest by Ookla β shows ping, upload/return speed and compares to other users of your operator.
- π FAST.com (from Netflix) β fast speed testing without data.
- π± Built-in test in Settings β SIM-maps and mobile networks β Network speed (not available on all firmware).
Pay attention to the following parameters:
- πΆ Signal level: if it is lower -100 dBm (can be seen in the engineering menu), the speed will drop.
- π Ping: if above 100 ms - possible lags in games and delays when loading pages.
- π Loading speed: for 4G the norm is from 10 Mbit / s, for Wi-Fi - from 30 Mbit / s (depending on the tariff).
If the speed is significantly lower than the operator's stated speed, the problem may be:
- π‘ Network settings (non-optimal mode) 3G/4G).
- π± Programmatic constraints MIUI (Background optimization, traffic limit).
- π§ Hardware problems (damaged modem, antenna).
