The situation where a high-speed plan fails to deliver the expected wireless network performance is familiar to many subscribers. Users often encounter the following: Rostelecom Internet The connection is unstable on devices connected over the air, while the speed matches the advertised speed when connected via cable. This creates the impression that the provider is underestimating the speed, although the root cause of the problem is often due to the characteristics of the radio waves, airtime congestion, or equipment settings.
In modern apartment buildings, the airwaves are saturated with signals from dozens of neighboring routers, microwave ovens, and Bluetooth gadgets. Wi-Fi router Forced to compete for available frequencies, this results in slower speeds, increased ping, and connection drops. Understanding the physical principles of signal propagation will help you diagnose and fix most problems yourself without calling a technician.
It's important to immediately differentiate between the concepts: if the speed is low on all devices (both cable and Wi-Fi), the problem may be on the provider's side or the backbone equipment. However, if via a wire 100 Mbps, and over a wireless network the pages barely load, then the problem is localized inside your apartment and is related to the router or its environment. Next, we'll examine the technical aspects that affect connection quality.
Radio channel congestion and neighboring networks
One of the most common reasons for poor Rostelecom Wi-Fi reception in an apartment is the high density of neighboring networks. In an apartment building, 10-20 routers can be connected simultaneously on a single floor. Most of them use the same standard channels by default, creating a "jam" effect on certain frequencies.
When your router attempts to transmit a data packet, it is forced to wait until the airwaves are clear of neighboring signals. This leads to delays and packet loss. The situation is especially critical in the range 2.4 GHz, where there are only 13 non-overlapping or partially overlapping channels. If all your neighbors are on channel 6, your network will experience constant interference.
To diagnose the level of airborne noise, you can use specialized utilities on your smartphone or laptop. They will display a graphical representation of all available networks and their signal strength. If you notice that your signal is being blocked by stronger neighboring networks, you should manually change the channel in your router settings to a less congested one, such as channel 1 or channel 11.
⚠️ Attention: Automatic channel selection (Auto) in routers often malfunctions, selecting the first available free channel upon startup, even if a neighboring router blocks it with its signal within five minutes. It is recommended to manually select the channel after analyzing the airwaves.
Problems with the 2.4 GHz vs. 5 GHz band
Modern Rostelecom routers, such as models Sagemcom or Sercomm, support operation in two frequency ranges. Old standard 2.4 GHz has good penetrating power, but extremely low speed and high susceptibility to interference. The new standard 5 GHz Provides high speeds, but is worse at passing through walls.
If your router broadcasts a network with the same name (SSID) for both bands, your device may "catch" on the longer-range but slower 2.4 GHz band, even when in the same room as the router. This creates the illusion of poor internet performance. Separating networks into different names (e.g., HomeWiFi And HomeWiFi_5G) will allow you to force high-speed gadgets to connect to the fast range.
Using the 5 GHz band almost completely eliminates problems with neighbors, as it offers numerous wide channels that are rarely occupied. However, it's important to remember that this signal is significantly attenuated when encountering obstacles. If there are two concrete walls between the router and the client, the speed on 5 GHz may drop below that on 2.4 GHz.
Physical obstacles and router placement
Equipment placement plays a critical role in coverage quality. A Wi-Fi signal is a radio wave that is reflected, absorbed, and scattered. Metal structures, mirrors, aquariums, and even walls with rebar can completely block the signal or create "dead zones."
A common mistake is installing the router in a niche, behind a TV, or in a closed (low-current) panel. The metal panel door acts as a Faraday shield, blocking the signal. Router antennas should be positioned in an open area, vertically, to ensure the antenna pattern covers the entire apartment.
The influence of household appliances should also be considered. Microwave ovens operating at 2.4 GHz can completely block Wi-Fi while heating food. Wireless baby monitors and older Bluetooth devices also contribute to background noise.
| Let | Impact on 2.4 GHz signal | Impact on 5 GHz signal |
|---|---|---|
| Wooden door | Minimum | Average |
| Concrete wall (15 cm) | Strong | Critical |
| Mirror / Coated glass | Signal reflection | Total reflection |
| Aquarium with water | Signal absorption | Complete absorption |
Outdated hardware and router firmware
Providers often provide subscribers with basic router models, which may not be able to handle modern plans. If you have a plan 200 Mbps and higher, and the router only supports the standard 802.11n (Wi-Fi 4), you won't be able to physically achieve speeds over the air. The maximum you can expect under ideal conditions is around 80–90 Mbps.
In addition to hardware limitations, software plays a significant role. Router firmware often contains bugs that can cause memory leaks or wireless module failures after extended use. This manifests itself in the router throttling or requiring a reboot.
Check your device's model. If it's a single-band router with a 5 dBi antenna gain, it may simply be underpowered for your space. In that case, purchasing your own dual-band router with support Wi-Fi 5 (AC) or Wi-Fi 6 (AX) will solve the problem radically.
How to check standards support?
Go to your router settings (usually 192.168.1.1) and find the Wireless or Wi-Fi section. If you only see b/g/n modes, the 5 GHz band is not supported. The presence of ac or ax mode indicates support for modern standards.
Security settings and third-party connections
Slow speeds may be due to your neighbors using your internet connection, or if your router has a weak password or uses an outdated encryption protocol. WEP (which can be hacked in minutes), outsiders can connect to your network.
Background downloads of game updates, watching 4K videos, or torrents on someone else's device will quickly eat up your bandwidth. Check the list of connected clients in the router's web interface. This section is usually called Status, Clients or Wireless Status.
It is recommended to use a strong encryption protocol. WPA2-PSK or WPA3 and a complex password consisting of letters and numbers. It's also worth disabling the feature. WPS, as it is one of the most vulnerable entry points for attackers.
⚠️ Attention: If you detect an unknown device, immediately change your Wi-Fi password and reboot your router. The old password may be stored on your neighbor's device.
Failures on the provider and line side
Technical issues on Rostelecom's end also cannot be ruled out. Fiber optic breaks in the building's entrance, equipment overload at the communications center, or scheduled maintenance could all cause speed drops. Unlike Wi-Fi issues, in this case, speeds will also be low on wired devices.
You should also pay attention to the cable running from the wall outlet to the router. If it's pinched, kinked, or has a loose connector, RJ-45, the negotiated port speed may drop from 100 Mbps to 10 Mbps. In this case, even the most powerful router will not be able to deliver high speeds.
To rule out line issues, connect your computer directly to your ISP's cable (bypassing the router) and run a speed test. If the results are low even via the cable, the problem is definitely not with your Wi-Fi equipment, and you should call technical support.

Frequently Asked Questions (FAQ)
Why does the internet work worse in the evening than during the day?
In the evening (7:00 PM to 11:00 PM), the provider's network experiences peak load. Thousands of subscribers are simultaneously watching videos, playing games, and downloading files. Furthermore, neighbors are using their Wi-Fi networks more actively, which increases interference.
Will a repeater help if the router has poor reception in a distant room?
A repeater can expand the coverage area, but it cuts the speed by about half since it operates in half-duplex mode. If you can run a cable to the far room, it's better to use a repeater. Access Point or configure routers in Mesh mode if they support this technology.
How often should I reboot my Rostelecom router?
It's recommended to reboot your device at least once a week. This clears the RAM of temporary errors and allows the router to reselect the least congested channel upon startup.
Does weather affect home Wi-Fi?
Not directly, the signal inside an apartment isn't affected by the weather. However, severe thunderstorms can cause power surges that damage equipment, and icing on external communication lines can lead to interruptions on the provider's end.
