View Full Version : Add Wireless to our existing network

Planning to add wireless capability onto our existing network purely
for visitors to our offices. Current network is DSL modem, connected
directly to firewall then switch which distributes to the network.
Two questions:

1. I want to connect the new wireless router directly to the DSL modem
and bypass our network completly - for security and bandwidth. any
issues with that or advice?

2. As the wireless will be directly connected to the DSL modem, how
can i limit the bandwidth being used on wireless? or put differently
what's a good wireless router that has feature to limit bandwidth?

I know I can connect the wireless router into the switch and have a
different subnet etc - is this advisable?

Thanks

This statement means nothing. Technically it doesn't matter if they are
visiting or permenant. What do you mean? Do you mean you want them to have
access to your network? No? Access to the Internet only and not your
network? What? I assume the latter, but, might they need to use your
printers?

Security for what? Connecting to the DSL modem wirless would mean they would
be on the same subnet as the outside interface of your firewall. If that's
okay... you're done.

If you want a selective bandwidth limiting device be prepared to pay big
bucks. Here's one:

Most folks probably do it this way.

If your firewall and switch can do VLAN, then you can have different subnets
for the private LAN and public LAN. Most Cisco firewall and switch can limit
bandwidth based on IP or subnet. router/modem with QoS may help some.

Hi
It is rather simple to do this with two Routers.
Here how; Network Segregation - http://www.ezlan.net/shield.html

Thanks Frank. Want them to connect to the internet only.
The external subnet wont be a problem as local network is shielded
behind firewall, with a different internal IP and subnet for local
network.
Thanks again.

Thanks Robert, will have a look at my equipment and see if QOS is
available.
Thanks Jack, this was helpful. Think I have a better idea now.
Very grateful for all your help.
