Slow internet through MTS 4G Wi-Fi router — a problem encountered even in areas with reliable coverage. Speed can drop due to incorrect equipment settings, network congestion, or external interference. In this article, we'll look at 15 Ways to Speed Up Your Internet, from basic checks to advanced settings for experienced users.
It is important to understand: The maximum speed of the MTS 4G router is limited by the tariff, but even within the same package, the actual throughput can differ by 2-3 times depending on the settings. We tested the methods on popular router models (Huawei B525, ZTE MF286D, MTS 821FT) and identified the most effective solutions.
1. Check your current speed and compare it with your tariff
Before optimizing your router, make sure the problem isn't with your data plan. Go to MTS personal account and check:
- 📊 Maximum speed according to the tariff (for example, “Up to 100 Mbit/s” does not mean a stable 100 Mbit/s).
- 📅 Remaining traffic — when the limit is exhausted, the speed may drop to 64–128 kbps.
- 🏙️ Coverage area — in some regions, MTS artificially limits speed during rush hour (18:00–23:00).
Take a speed test on Speedtest or Yandex.Internetometer, connecting to the router via cable (via LAN port). If the speed difference between Wi-Fi and cable is more than 30%, the problem is in the wireless network settings.
2. Optimizing the router location
4G signal (LTE 800/1800/2600 MHz) is sensitive to obstacles. Even glass partitions or an aquarium can reduce speed by 20-40%. Follow these rules:
- 📡 Height — place the router at a height of 1.5–2 m from the floor (for example, on a cabinet).
- 🚫 Avoid proximity to microwaves, cordless telephones, wireless speakers.
- 🌿 Plants and aquariums absorb the signal - do not place the router near them.
- 🔄 Antennas - If they are removable, rotate them at a 45° angle to each other for better coverage.
To check the signal level, go to the router's web interface (192.168.1.1 or 192.168.8.1) and find the section Status → Network → Signal StrengthOptimal values:
| Parameter | Good signal | Weak signal |
|---|---|---|
| RSRP (dBm) | from -70 to -90 | less than -105 |
| RSRQ (dB) | from -10 to -15 | less than -18 |
| SINR (dB) | more than 15 | less than 5 |
⚠️ Attention: If the value RSRP worse than -110 dBm, the router is at the edge of the coverage area. In this case, only external antenna or change of operator.
3. Changing the Wi-Fi frequency range
Most MTS routers operate in two ranges: 2.4 GHz (distant, but overloaded) and 5 GHz (fast, but with a smaller coverage area). By default, the router may use suboptimal settings.
How to change the range:
- Log in to the router's web interface (logins/passwords are usually on a sticker at the bottom):
admin/adminoruser/user). - Go to
Wi-Fi Settings → Basic Settings. - Select mode:
- 📶 5 GHz only - if the devices are close to the router (up to 10 m) and support this range.
- 📶 2.4 GHz only - if you need a larger coverage area (but the speed will be lower).
- 🔄 Dual band (2.4 + 5 GHz) — optimal for most cases.
- For
2.4 GHz—20 MHz(more stable). - For
5 GHz—40 MHzor80 MHz(faster, but may lag when there is interference). - Go to
Settings → System → Firmware Update. - If a new version is available, update. Do not turn off the router during the process (may become "bricked").
- After updating, perform a factory reset (
Settings → System → Reset).
Select 5 GHz band (if supported by devices)|
Set channel width to 40-80 MHz for 5 GHz|
Disable 802.11b Compatibility Mode (Legacy)|
Enable WPA3 (if available) for security without sacrificing speed-->
For advanced users: If your router supports it, enable it. MU-MIMO And Beamforming in the Wi-Fi settings. These technologies distribute the signal more efficiently between devices.
4. Updating the router firmware
Outdated firmware may limit speed due to errors in modem drivers or routing algorithms. Check your firmware is up-to-date:
For routers Huawei B525 And ZTE MF286D The latest firmware can be downloaded from the official websites:
- Huawei: consumer.huawei.com/ru/support
- ZTE: ztedevice.com.ru
- Go to
Settings → Advanced → QoS. - Enable QoS and select the mode:
- 🎮 Games/Videos — priority for
UDP traffic(For example, Twitch, Zoom, online gaming). - 💻 Job — priority for
TCP ports 80, 443(web surfing, cloud services). - 📱 Custom rules — manually specify the MAC addresses of devices that need more speed.
- 🎮 Games/Videos — priority for
- Save the settings and reboot the router.
⚠️ Attention: Firmware from third-party websites may contain malicious code. Use only official sources.
What should I do if my router won't turn on after updating?
If your router stops responding after updating the firmware, try:
1. Turn off the power for 30 seconds, then turn it on again.
2. Press and hold the button Reset for 10-15 seconds (full reset).
3. If this doesn't help, contact MTS support with your purchase receipt for a warranty replacement.
5. Configuring QoS and traffic prioritization
QoS (Quality of Service) Allows you to prioritize speed distribution between devices. For example, you can prioritize maximum speed for your laptop while limiting the speed of your smartphone, which is downloading updates in the background.
How to configure QoS on MTS routers:
Example of a manual rule for prioritization Zoom:
Protocol: UDPPorts: 8801-8810
IP address: * (any)
Priority: High
6. Using an external antenna or repeater
If the 4G signal is weak (RSRP < -105 dBm), an external antenna can increase speed by 2-5 times. MTS supports antennas with a connector TS-9 or SMA (depending on the router model).
Top 3 antennas for 4G signal boosting:
| Model | Gain (dBi) | Price (2026) | Suitable for |
|---|---|---|---|
| Poynting XPOL-2 | 9–11 | ~3 500 ₽ | City, suburb |
| LTE MIMO 2x2 | 7–9 | ~2 200 ₽ | Dacha, weak signal |
| TP-Link TL-ANT2408CL | 8 | ~1 800 ₽ | Budget option |
How to connect the antenna:
- Purchase an antenna with a connector compatible with your router (check the documentation).
- Unscrew the standard antennas of the router and connect the external one through
pigtail(adapter). - Point the antenna towards the nearest MTS tower (find it on the map) CartoGIS).
⚠️ Attention: Installing an ungrounded antenna during a thunderstorm is dangerous! Use a lightning arrestor (costs about 500 rubles).
7. Alternative methods: VPN, DNS, MTU
Sometimes speed drops due to operator blocking or suboptimal network settings. Try:
- 🔒 VPN — Some providers throttle traffic to certain services (for example, torrents). Free VPNs (ProtonVPN, Windscribe) can bypass the restrictions.
- 🌐 DNS - replace MTS DNS (
77.88.8.8) on1.1.1.1(Cloudflare) or8.8.8.8(Google). This will speed up website loading by 10-30%. - 📏 MTU - If the pages load slowly, but the speed according to the test is high, reduce
MTUto1400in the router settings (Settings → Networks → WAN). - Go to
Settings → Networks → WAN. - Find the fields
Primary DNSAndSecondary DNS. - Enter
1.1.1.1And1.0.0.1(Cloudflare) or8.8.8.8And8.8.4.4(Google). - Save and reboot the router.
- 🔄 Hard reset - click
Resetfor 10 seconds, then configure the router again. - 📱 Replacing the SIM card — old SIM cards (Mini-SIM) may limit speed. Order a new one. Nano-SIM in the MTS salon.
- 🏆 Test another operator - If the MTS signal is weak in your region, check the speed at MegaFon or Beeline (buy a test SIM).
- Huawei B535 - support
4G+and external antennas. - ZTE MF286R — two antenna connectors, speed up to 300 Mbps.
- Use range
5 GHz. - Reduce the number of connected devices.
- Update the Wi-Fi adapter driver on your PC/laptop.
- Change your Wi-Fi password to a complex one (at least 12 characters with numbers and special characters).
- Enable MAC address filtering (section
Wi-Fi → MAC Filter). - Turn it off
WPS- This is a vulnerable protocol. - Use QoS to prioritize important traffic.
- Connect to the network via VPN (sometimes helps to avoid throttling).
- Check your plan—it might be worth upgrading to an unlimited plan with guaranteed speed.
- Setting up the router (as described above).
- Updating network card drivers on a PC.
- Windows optimization (
netsh int tcp set global autotuninglevel=restrictedin CMD).

8. Extreme measures: reset, SIM card replacement, alternative operators
If nothing helps, try:
If your router is older than 3 years, its modem may not support modern standards (for example, LTE-Advanced). In this case, the only solution is to replace the device with a new model, for example:
⚠️ Attention: Before purchasing a new router, check the list on the MTS website certified devicesSome models may not work with MTS SIM cards.
FAQ: Frequently Asked Questions about Increasing Speed
❓ Why is my Wi-Fi speed slower than my cable speed?
This is normal: Wi-Fi loses up to 30-50% of its speed due to interference, distance, and standard limitations (e.g. 802.11n maximum 300 Mbps, and 802.11ac — up to 1 Gbps). To reduce losses:
❓ How can I check if my neighbor is stealing my Wi-Fi?
Go to the router's web interface (192.168.1.1) and open the section DHCP → Clients or Wi-Fi → Connected devicesIf you see unfamiliar MAC addresses:
❓ Why does the speed drop in the evening?
This is called the "Thursday effect"—network congestion during peak hours (6:00 PM–11:00 PM). MTS may artificially limit speeds for all users in the area. Solutions:
❓ Is it possible to increase the speed using a program?
No, programs like «Internet Speed Booster» — these are dummies or malware. Only the following actually work:
❓ What is the maximum speed of MTS 4G routers?
The theoretical maximum depends on the router model and standards support:
| Router model | Max. speed (Mbps) | 4G+ support |
|---|---|---|
| Huawei B525 | 300 | No |
| ZTE MF286D | 150 | No |
| MTS 821FT | 100 | No |
| Huawei B535 | 300 (LTE-A) | Yes |
Actual speed is usually 30-50% lower due to interference and network congestion.
