I recently posted a plan to upgrade my network at my company because of poor preformance and such.
I was urged to go and switch to fiber but that was not in the cards.
Upon installing what I did install, the network is fantastic and works quicker then ever and smoothe to boot.
However, the problem I am having now, is that the INTERNET will give out and I have to reboot the whole network to get it back.
I have a 10/100 linksys router connected to a dsl modem, which goes into a 24 port switch which is all 1 gb and each machine has 1 gb cards with cat 6 cabling. the dsl says it has a signal.
I am assuming that the router is the cause of the problems, because the network itself works wonderfully. The internet will give out once every couple weeks or less, enough to cause a problem but not too often.
unfortunatly i have been sick and am not at the shop to look at what models i have but perhaps if you have any idea what would possibly cause it i can look into it, i can post more details when i am back to work if needed.
You could slip in a transparent proxy, bandwidth monitor, throttle those that are hogs... but monitoring your devices would be the best way to go (like seacliff stated), it will help find the point of failure.
This kind of stuff should not be happening! How many PC's and servers do you have?
Also check for firmware updates for your router... Sounds like you did everything backwards... When upgrading network equipment, you should always go from the front to the rear, meaning router gets upgraded first then the switches...
