Setting up Cisco Aironet 1250 for home use

Hey everyone,

I'm rather new to the whole Enterprise Router lines. I've set up countless networks with Linksys routers in the past. However, this Aironet is giving me more trouble than I'd want it to. I was wondering if anyone could help. I've assigned it an IP Address and accessed that In-Browser interface and set up an SSID and activated the two extensions. I've been able to connect to the router with my computer and access the internet without restriction. However, when I attempt to connect a second PC or Laptop to the network, it won't allow network access to the second device. I've been stuck there forever. Is there any specific setup method I need to use to make sure more than one workstation/device? I want to use this router for home use, I often use laptops and move around the house a lot, so the advantage of better connection signal and speed is well worth it. Any help is highly apprieciated. If you need more information, don't hesitate to contact me.

Re: Setting up Cisco Aironet 1250 for home use

Multiple devices should be able to connect with out an issue.  Did you set any values for number of connections?  Can you attach the config?

Re: Setting up Cisco Aironet 1250 for home use

Not that I know of. I never set any values for the number of connections. I used the In-Browser interface to set it up. I don't know how to get the config stats, can you help out with that? Thanks for your time.

Re: Setting up Cisco Aironet 1250 for home use

It would help to know how the 1250 is connected to other devices in the network.  Is the 1250 your only device and connected directly to a router or modem?  Is it plugged into a switch?  If you can give me some more info, I can get you through configuring the AP.  If you know how to connect to the AP using a console cable, login.  Assuming you didn't remove the default account, you should be able to reach the user level mode immediately, which is usually the hostname 'ap>'.  The forward caret tells you you're in user mode.  Enter the command 'enable' and it will ask you for the enable password.  By default it's 'Cisco'.  If you did it right, your prompt will change.  Again, if the AP is still has a default host name, you'll see 'ap#'.  The pound sign tells you you're in privileged mode.  You can now dump the running configuration by typing 'show running-config'.  Copy and paste to a notepad file and post here.  You can also download the config via the GUI, but I'm so adept these days at the command line that I actually forgot how to do that!

Re: Setting up Cisco Aironet 1250 for home use

The router is connected directly to my modem by means of a power injector over POE. It's the only router in the network. I do know how to use the CLI to an extent, so I'll get the config up soon. Thanks for the help so far.

Re: Setting up Cisco Aironet 1250 for home use

Thach -

You said your router is plugged into your cable modem by means of a PoE injector.  Please clarify for me if you mean to say 'ap' instead of 'router'.  If you are plugging your AP directly into your cable modem, then the AP would have to be performing NAT and routing, something I'm not sure if the 1250 supports.  I will have to look further at the config guide once you tell me your logical diagram.  If you could, show me something like this (which is how my 1250 is connected):

TW cable modem ----> Cisco 881w Router ----> Cisco 3548XL Switch ----> Cisco 1250 AP

Re: Setting up Cisco Aironet 1250 for home use

What I guess is happening (I have the similar situation with my cable modem) is that the cable modem acts as DHCP server for 1 ip address (it expcets one workstation or a NAT router).

The laptop that connects gets this ip address.

Unless you configure NAT, you can't have multiple devices.

They way I connect it in the network is as follows:

BrightHouse Networks ISP Modem --> Cisco Aironet 1252 --> Incoming connections from computers and laptops.

Any ideas?

Re: Setting up Cisco Aironet 1250 for home use

Is there any news on how to do this? I think what I need to do is set up an NAT as someone suggested before. I need some help on how to do that. Thanks.

Thach -

I'm your man, but I've got a newborn at home and a 3 year old.  Plus it's Thanksgiving weekend, so I'm recovering from having had guests overnight at my home.  I'll try to get to it tonight or Sunday night.

Re: Setting up Cisco Aironet 1250 for home use

Thach -

A quick search through the IOS Command reference guide for the most current IOS release of the 1252 doesn't show any NAT support.  This is also confirmed with the command lookup tool.  I'll do a final verification with my AP at home, but it's doubtful that your config will work.  You'd need a router in between the cable modem and AP at a minimum, as NAT is typically a function that operates on a router or other L3 device (i.e. multilayer switch).

Regards,
Scott

New Member

Re: Setting up Cisco Aironet 1250 for home use

So, you mean I would have to have a router in between the router and AP?

In such case, would this work?:

Modem --> TM VOIP Linksys Router --> Cisco 1250 AP

NOTE: I've already tried to set it up this way, it also did not work.

I can easily reset the AP the factory defaults and set it up again if there is any way to do it. Your help is very apprieciated.

Re: Setting up Cisco Aironet 1250 for home use

Thach -

Yes, that would work - assuming that VoIP router supports NAT.  Some VoIP routers are strictly VoIP only, and are really only ATA devices that convert IP packets to analog for a phone.  What is the model of the Linksys product you speak of?  Is it the kind you get when you purchase services such as Vonage?  I could setup a time to 'conference' with you.  I use the free LogMeIn service at https://join.me.  It supports remote control and chat.  This way, I'd be able to look at the devices in your network and get a better understanding of what they support.  I'm on the east coast in UTC -5 timezone.  What works for you?

Scott

Re: Setting up Cisco Aironet 1250 for home use

Scott,

     This is an WRTU54G-TM Linksys VoIP home network router. I also live on the East Coast, UTC -5. I do believe the router supports NAT, when I hook up the AP to one of the router's Ethernet ports. It works with multiple clients fine, but doesn't supply internet. I'm open 5PM Saturday, I'll see what we can dp. Thank you for the help, Scott.

Re: Setting up Cisco Aironet 1250 for home use

Hey, Scott.

I've just figured it all out. I had to run the AP through the router to have it work, but it kept turning up problems. I had a past issue like this so I changed the ip add of bvi1 to 192.186.0.254 so it wouldn't have an ip conflict with the router's ip (192.168.0.1). Thanks for all the help. It works now, so all's well that ends well. Thanks again!

Best regards,

Re: Setting up Cisco Aironet 1250 for home use

Hi,

1250 AP is a layer 2 device only. NAT cannot be done on AP.

NAT is to be done on a layer 3 device like a Router.

Re: Setting up Cisco Aironet 1250 for home use

Hi guys,

Me again, so I was thinking about what you've suggested with using a switch for the AP. I found an old Linksys SD208 8 port 10/100 switch at the thift store. I came home and set everything up and found that the AP will again refuse to accept more than one client at a time.

Here is the set-up

Internet

-> Modem

--> Linksys Switch

   --->Port 1

             -Internet from modem

   --->Port 2

             -Cisco Aironet 1252 AP

   --->Port 3

             -T-Mobile Linksys WRTU54G-TM Router

   --->Port 4

            Empty

   --->Port 5

            Empty

   --->Port 6

            Empty

   --->Port 7

            Empty

   --->Port 8

            Empty

The router works fine, it's just the AP that is acting up.

Thank you for the help!

-Thach

Re: Setting up Cisco Aironet 1250 for home use

As we already mentioned, the AP doesn't do NAT and doesn't share internet connection, it's not a router. So it needs to be behind a NAT router.

Re: Setting up Cisco Aironet 1250 for home use

Thach -

I'm not sure what the Linksys supports, but you'd have to do 'router on-a-stick' since the Linksys probably only supports L2 functionality.  Make sure the router is connected to a trunk port on the switch and that the native VLAN is set correctly on the trunk.

Regards,
Scott

New Member

Re: Setting up Cisco Aironet 1250 for home use

I see.

Well then, what switches are capable of supporting NAT? I'd rather not link it though the router, as it slows down transfer speeds.

Thanks again for the prompt help.

Re: Setting up Cisco Aironet 1250 for home use

Thach -

You need a multilayer switch then.  They're not cheap.  You could get a 2960 or 3560 8 port switch that does L3.  You might be able to find something on eBay or Craigs List.

Scott

Re: Setting up Cisco Aironet 1250 for home use

Would this one work?

-Thach

New Member

Re: Setting up Cisco Aironet 1250 for home use

Thach -

That one definitely will not work.  I gave you model numbers of some current generation equipment that will support L3.  The oldest switch I can think of that might support layer 3 is the 3550 series with the enhanced image, but that's an assumption I'm making (I'd have to actually research it).  If it were me, I'd attempt to use the setup you have to make mysefl (i.e. you) stronger at understanding and configuring network technologies.

Regards,
Scott

New Member

Re: Setting up Cisco Aironet 1250 for home use

Thach -

My 3550 XL does support 'ip routing' and 'interface vlan x', which are indications that the box supports some layer 3 functions.  But the current IOS does not support NAT, and the feature navigator doesn't show that any of the old stuff does (that's why I suggested at least a 2960/3560).  Again, this is because layer 2 boxes don't support NAT.  This is why we call switches that do support them 'multilayer'.  These are expensive due to the ASICs required to perform that work.

Scott

Re: Setting up Cisco Aironet 1250 for home use

Ok, another update, and thanks for the help so far.

I've just made a purchase for a Cisco 2960 8 port switch ( Exact model: WS-C2960PD-8TT-L ), I reckon this is what I need, so far I've gone through the Express Set-up and configured it through there with no problems. I've set upthe hardware in the following manner:

-Internet Modem

>Port 8 on Switch

->Port 1 on Switch goes to 1252 Cisco AP

->Port 2 on Switch goes to Linksys VOIP home Router

I let it set up and can connect to the internet through the AP, and through the router. (I'm posting through the AP-Switch set-up right now.) However, once I connect to the AP with a second client. It refuses to work, as it would a direct connection/the linksys switch I tried before.

I'm going to assume this is due to NAT not being configured through the command line on the switch yet. I'll look into that, any advice on the set-up/suggestions are highly welcomed. Thanks in advance!
