To start with, you want to avoid placing your router close to metal objects and appliances that emit electromagnetic waves. Not all places are equally suitable for your router. Now that you understand the top 5 factors that affect WiFi performance, it’s time to take a closer thing at some of the things you can do to improve it. However, these features may need to be manually enabled to work, and older routers often don’t support them at all.
The measured download and upload speeds should correspond to the speeds advertised by your ISP. To test if that’s really the case, connect to the internet via a wired connection and perform an internet speed test.
You can’t reasonably expect a low-end router to provide reliable wireless access to the internet to a busy office with more than a dozen of employees and several fax machines, WiFi connected printers, and wireless security cameras.
