If your internet connection is slow at the office, do the following tests:

• Copy a large file (more than 100MB) from one of the local servers to you. If the copy speed is low, then there’s an issue with the WiFi. Try reconnecting, it might help.
• If the copy speed is acceptable, do a speed test using Speedtest.net. If the speed is high (more than 250Mbps) then there are no issues connecting to Armenian networks.
• Try doing a speed test using https://librespeed.org/ , make sure you use a Western European server such as Amsterdam or Frankfurt, if the speed is low, then there’s an issue at IIAP.
