Over the past few weeks my org has been experiencing the following issue.
Browsing speeds are very slow to the internet but browsing internal resources is fine.
I will try to provide as much info as possible...
Bandwidth - Time Warner Cable 20 down 2 up
Router/Firewall - Sonicwall NSA 240 (latest firmware)
Switches - HP Procurve gigabit (latest firmware)
Users - 100
- We have spoken at length with Sonicwall who insists it is not their device and we do not have a virus issue since we dont have an abnormal amount of connections
- We are seeing some collisions on the HP on certain ports where other down level (8 port switches) are plugged in. But these have been the case for over 2 years
- We have tried using different DNS and same issue
- We have tried multiple browsers, chrome, IE, firefox
Ran multiple AV scans on all machines and came up with nothing.
So here is what happens.. go to a page say yahoo.com and click on a link.
Loading, loading..................... times out
So heres the kicker... before 9AM and after 5:30 PM the speeds are super fast.... during the day they are bad.
How do we go about trying to find out what is happening during these times??!
