What's Causing Slow Internet Speeds For Your Employees?Aug 09 , 2018
Are your employees frustrated with slow internet speeds? Before you call your ISP and increase your bandwidth, it's best to determine the root cause.
There are several factors that could be causing a slow user experience. Router, firewall, malware, bad cables, employees streaming media, packet prioritization and ISP-related issues could all be culprits to slow internet speeds or high latency.
With so many possible saboteurs to broadband performance, you’ll want to be systematic in your approach to identifying the problem. Start with the connection closest to the internet, and work your way back to your users, device by device, until you isolate the point of the problem.
Test Your Internet Connection
Your first test should be the internet connection. If you’re using a business-grade Internet service, your ISP can run several tests. The most accurate test is the direct connect test. Here, your internet service provider will test your broadband connection at the Demarc - the point at which your internet connection is handed-off to your router/firewall. If your internet connection is
If speed and latency test results meet the performance standards of your internet service contract, then the problem is within your network. Most often performance is not intermittent, but regular in nature. So if the direct connect test shows all is well, then move to the next device.
Test Your Router/Firewall
If your results show slow speeds or high latency then you’ve identified the router/firewall as the culprit. Inspect your wired connections to make sure there are no physical issues. Check rate limiting settings, packet prioritization configurations, and interface settings such as speed and duplex. (Normal interface settings are GigE/FastE and Duplex Auto.)
Check for errors on the interface (PHY/CRC), which if exist, will point to bad cables or connectors. Have you outgrown your firewall capacity? If your CPU load is 80% or greater with full user load, then it’s probably time to upgrade your firewall.
Test Your Switch
Connect to the speed test behind your
Continue Testing in Isolation
Continue testing each device in isolation until you find the problem device. This can be a tedious process for many IT professionals, and often the interruption to users is less than desirable. If you can test after hours, this would be the way to go.

Most Common Causes of Slow Internet
Our experience as a business-grade ISP has shown that the most common root cause is attributed to insufficient bandwidth.
Most often, the high bandwidth use is due to employees transporting more data volume than the company realizes. The growth of BYOD and streaming media often causes companies to underestimate their bandwidth use. If customers need more bandwidth, we can quickly and easily increase it to the right amount.
Another common problem is packet prioritization. If you are using real-time services like VoIP or video conferencing, you need to prioritize these packets above other data packets if you want a good user experience. Make sure your packet prioritization is properly set in both your router and
