netowrk with 2 ISPs.



Hi all.

2 ISPs are configured in 2 broadband routers with LAN IP and
terminate in 2 different networks. ( 1 hub with 5 workstations and 1 switch
with 15 workstations ) thus not conflicting. IP range 100 - 120 and gateway for all workstations. When one of the ISP goes down, i d/c the
LAN port of router from specific switch ( to avoid ip conflict ) and connect
another cable "switch to hub" trying to shift traffic to other switch / hub
automatically. This sometimes works, sometimes does not. If it doesnt, i have
to disable enable ethernet card manually to make it work. Workstations show timed out until disabled and re-enabled.
Looking for something that would work for sure.. Would a switch instead of
hub work? Any other way i can do this just by shifting cables?

I can't even begin to comprehend how you've got this set up. It sounds like
you've got two routers running two ISP's and actualy running on two
different networks...but when one goes down you link them together....but i
completely totoally get lost at how you've got it hooked up, i'd have to see
some kind of graphical network map.

i'll tell you this though...if you don't need two seperate networks and are
only doing this because of the dual connections, you'd be better off to get
a load-balancing switch of some's got two wan ports so you connect
your ISP's directly into it and connect your entire network to it. it'll
share the bandwidth of both with everyone, giving 2x speed and
load-balancing features. It'll also automatically roll-over to the working
connection should one die.

I'm sure how you're doing it is fine...but the whole running TWO routers on
seperate networks and trying to "splice" them together for internet
functionality is probably causing problems....if both routers are handing
out IP's, it's possible you're getting ipconflicts. I'd seriously consider a
major overhaul in how the network is configured and pick up a router
designed for this...i saw one for $99.99 at microbarn (TP-Link TL-R480T+)
