Wifi setup for a conference with around 70 users

Hello I have a small office with small network of users that are all wifi but they have a conference one a year that they invite alot of people that require internet with their laptops we have test this before with the Verizon wifi router that in place and had drop outs... some users connected but would suddenly loose connection, can you help me point me in a direction of what I can purchase and setup to allow about 70 wifi connections all in one room ... Also cost is a factor, really don't want to purchase anything big for something that is only once a year?? Any suggestions

look at Ubiquiti Unifi APs. They are quite good.

Ok, my concern is with most extenders I seen in the past the externder has a different SSID but the same WEP password, do I tell some of the users to log into one ssid and other into the other, it seems to me that would be a bit confusing. What would be the best way to have everyone connect with out making it so confusing with the SSID's

I use these in the office connected behind our firewall and use them for conferences and meetings when required, haven't had any issues or complaints.

First, I think the discussion should be about Access Points and not Extenders.  The differences are substantial.

You didn't say that you could not use an Ethernet connection to this device.  If you can, then you should.

If you can't use an Ethernet cable then I'd suggest an Ethernet powerline extender pair.
While you can get a pair with one having a wireless access point built in, it's harder for me to tell you that this is a good idea due to lack of experience.  So I have to recommend a pair that's for Ethernet only.
You plug an access point into the remote Ethernet connector.
A common approach with an access point is that it will have it's own DHCP server which is restricted to its own wireless network and won't interfere with the LAN DHCP function.  
The DLink DAP-2360 is such a device.  NOT ALL access points have a built-in DHCP server!!
Just make sure that the DHCP address range doesn't interfere/overlap with your LAN DHCP range.
Better: put this Ethernet link on a separate VLAN and you don't have to worry about address range overlap.  You didn't say, but I might assume, that you don't want *anyone* using the Conference WiFi to not connect into your local LAN. So that makes the notion of using a VLAN even that much more important.
(And, there are some "poor man's" ways to get the effect of a VLAN if your equipment doesn't have the capability).


There will be no issues with SSID nor Security unless you create them on purpose.
Fred MarshallPrincipalCommented:
If you don't mind having all those Conference guests on your local LAN then you can do away with the DHCP considerations and VLAN considerations and just let your local DHCP server do the work.
Just make sure your DHCP address scope is adequately large to serve 70 new clients AND make sure the lease time is set to be short.  In this case, I'd make it 1-2 hours.

Thanks everyone, Fred you recommendation is more in the direction I think will work without a lot of work, the local network doesn't have any server or any concerns about the guest being on the network they have the wifi password posted on the wall so anyone that comes into the office can use the network, but my question is witch device is better for this option, also I do have an Ethernet connection and power  in the conference room so I do have a hard wire connection.  Also the SSID was a big concern I really didn't want to have to tell some people connect to one SSID and others another.  Thanks everyone all help is greatly appreciated

Thanks for the points.  I'm glad this helped.

If you really want this to be simple and inexpensive then you could consider a commodity wireless router connected as a "switch and access point".  It's a very common approach.  
The attached shows how.

I don't know why it doesn't show that way here nowadays.  It always has before.
