I came home to visit my parents and noticed that they did not have any security for their old Linksys Router.
So I factory reset the device (they had created an admin password and then forgotten it) and then went into the settings and enabled wireless security and secured the wireless with a password.
After doing this everyone on the network (including those hard wired) have been experiencing extremely long web page loading that had not existed before. It is as if the browser would get hung up on something and then after a while begin to piece the webpage together.
I was wondering if anyone had any advice or suggestions.
Also, along with another reset, you might want to check and see if a firmware update is available for the router. Often times routers have a built-in section for applying firmware updates.
If possible, use WPA2/AES for security, enable WMM, and don't use channel bonding.
Has anything changed in the physical location of the router? Perhaps you have new interference you have overlooked, or the orientation of the antenna(s) has moved. How much signal strength are you receiving at each computer, and what kind of throughput are you getting on file transfers between machines using only the local network?
Have you tried an internet speed test to see what is happening with your connection to the outside world?
Perhaps do a speed test with one machine wired to the internet, bypassing the router, to confirm you're not chasing ghosts.
