Internet users may pay for a certain broadband package but sometimes receive less than half the advertised speed. The cause can lie with the provider’s overloaded network, an aging line, an outdated router or interference inside the home, according to Azerbaijani cybersecurity expert Farid Musayev.
Musayev, a specialist with the Azerbaijan Cybersecurity Organizations Association and head of information technology at Khazar University, discussed the issue in comments cited by Vesti Baku from Demokrat.az.
Where Speed Can Be Lost
Older subscriber lines, ADSL connections and poor-quality copper wiring can weaken the signal and reduce the speed that reaches a customer. Congestion also occurs when multiple households share network infrastructure, particularly during peak evening hours.
Inside the home, Wi-Fi performance can deteriorate because of thick walls, neighboring wireless networks and the number of connected devices. Interference is especially common on the 2.4 GHz band. An old router may itself become the bottleneck even when the provider’s line is performing normally.
Test With an Ethernet Cable
Musayev recommends connecting a computer directly to the router with an Ethernet cable before blaming the provider. Users can then run tests through services such as Speedtest.net, Fast.com or Cloudflare Speed Test.
The test should be repeated at different times of day, including during the evening. If results are close to the subscribed speed during the day but fall sharply at night, congestion on the provider’s network is a likely explanation.
For a 50 megabits-per-second package, Musayev said a wired result below 80% of the plan - less than 40 Mbps - warrants investigation. Ping and jitter also matter for video calls and online games: high or unstable delay can disrupt those services even when the download rate appears adequate.
A single poor result does not by itself prove that the provider is at fault. Repeated low readings over a wired connection, however, give the customer evidence for a technical complaint. The essential first step is to determine whether the loss occurs on the provider’s line or within the home network.
