Question about Access Point

[Eliana.Barreiro]

Hello

In my work, we have two WAP4410N Wireless-N Access Point with Power Over Ethernet, but ¿how many users support each access point? And, somebody knows how I can configure the two access point to be viewed as one in all laptops? Normally, the laptops found access point 1 and acces point 2 but, somebody says me I can configure them as if they are one.

Thanks

yeah  you can configure both APs as one

just configure same SSID on both and tag vlans to them.

As a broad rule of thumd you can support ~20 users per AP. The previous post is correct all you need to do is configure the same SSID on both APs to have them appear as one and to facilitate roaming. If you support mutiple VLANS and SSIDs you will need to configure the switchport as a trunk port.

Thanks for your answers. I configured the SSID with the same name and it works! But I have another question, when the access points works as one, the quantity of users supported are 40?

And I have another trouble, the access points shows null or limited connectivity but I don't know why.

Thanks.

Eliana,

     The rule of thumb is a typical Ap can handle 20 users each, but the actual capacity could be more or less, alot of it depends on the traffic the users are generating and the bands/protocols.

for example if you are using 802.11g @ 54mbps, in reality your getting roughly 36 mbps of actual throughput, so then you have 20 users each using 100k of bandwidth which is about 2mb of traffic, you could handle more, but if you have 10 users that are pulling 1.5mbps then your cumlative traffic is 15mbps; so load is traffic dependant.  Retries and other issues can affect this as well but are hard to calculate.

Also make sure the 2 access points you setup are on different channels.

Null or limited connectivity?? do you mean low signal strength or no network access?

Hope this helps.

Null or limited connecvitity -- ? Are you using a WIN 7 client? This norally means there is no access to the internet.

I realize this is a late reply but it sounds like your clients may not be getting an IP address. I have experienced a problem with Windows 7 clients not getting an IP address from Cisco DHCP servers such as the ones embedded in a router or a controller. I have had to use the workaround of putting an IP helper address on the interface of the router and directing the DHCP discover packets to a microsoft DHCP server.

I don't have Windows 7 clients, all are Windows XP clients. Before I  have two access points 3COM and doesn't show this problem. The access  points are configured with an IP.

I believe that the issue is not that the APs don't have an IP address it is that the clients asociating to the APs are not getting an IP address. Is your DHCP server on line and reachable from the clients associating to the APs? Is your DHCP information correct in the access points?
