Factors affecting actual speed
Factors affecting actual speed of fiber optic broadband
Actual Internet access speed is affected by multiple factors, so is less than network specifications might suggest. Common influencing factors are:
Computer configuration
Poor computer performance is a common reason for slow speeds. Frequent causes are:
  1. Poor performance processor
  2. Speed of hard disk
  3. Insufficient memory
  4. Computer Virus or Spyware
  5. Old and unstable operating system
You may refer to How to maximize the bandwidth performance for more details about checking the current settings of your computer system and making adjustments to match the recommended settings.
Devices connected simultaneously to same network
When multiple connected computers or devices – such as a mobile phone and wireless router – connect simultaneously to the same network, the result of having to share the available bandwidth, Internet access speed could be reduced.

Wireless router specification is extremely important in this regard. If a router that does not support high speed is connected, Internet access speed will be correspondingly reduced. For example, if you are using 10G fiber optic broadband service and your wireless router only supports up to 1000Mbps, the highest possible Internet access speed will only reach up to about 1000Mbps.
Wireless network
Wireless connection throughput is subject to conditions such as the local radio environment, number of devices sharing the same wireless network, range of the wireless coverage, interferences, physical obstacles and capability of receiving end. As a result, actual wireless connection speed will be less than the maximum throughput.

Many users enjoy internet access via wireless routers. However, with many options of wireless routers available in the market, you may find it useful to refer to Wireless router report for details and specifications of some models we recommend and choose the suitable one for your broadband.
Transmission bandwidth of network server and network condition
Each website is served by a server connected to the network, and network bandwidth is distributed according to a website’s usage. So when the number of users is low, your connection speed will be faster. In contrast, when the number of simultaneous users is high, your linking network server will be congested, causing the connection speed to drop, especially for an overseas network server and the amount of users.

In summary, the end-to-end data throughput is also dependent on the bandwidth of the connection from the web or network server to the internet.
Utilization of other instrument or software
Internet connection speeds differ and depend on what other services are being used at the same time – e.g. web browsing, internet television and so on. Bandwidth demanding applications such as file sharing, video conferencing, and watching online movies, and software used will also influence internet access speeds, as they consume bandwidth, as well as processing power of your computer.

Note 1:
Bandwidth Specification refers to network specifications of the subscribed Services for the broadband line connected from the modem at your Premises to the first piece of network equipment or central office of the NETVIGATOR network. For Fiber-to-the-home Plans, bandwidth specifications of 100M, 200M, 300M, 500M and 1000M correspond to a maximum upstream and downstream bandwidth of 100Mbps / 200Mbps / 300Mbps / 500Mbps / 1000Mbps respectively. For bandwidth specification of 10G, maximum downstream bandwidth is 10Gbps and maximum upstream bandwidth is 2.5Gbps. The actual speed you experience using the Service will be less than the network specifications and affected by your device, technology, network and software used, network configuration and coverage, usage levels, international bandwidth and extraneous factors.
