Cisco Wireless :: 1240AG Extending Wireless Network
Nov 8, 2012
I have an Aironet 1240AG. I resides inside a building with its antenna placed on the outside of the building. In direct line of site, I have a light pole to which I could attach another wireless access point to extend my wireless network. This access point would have to be "rugged". Also, it would have to be able to be bridged to the current access point. In reviewing outdoor wireless access points, it appears that the 1552 is the way to go.

I live in a house with three floors. I have a Virgin Media Superhub on the ground floor with the 30MB package. Whilst the wireless signal quality and speed is good on the ground and first floor, it is intermitent on the second floor and my son wants to connect his PS3 with a wired connection for speed.
I have a N wireless router that I was using before I receiced the new Virgin Superhub. I want to ask if I can connect the old wireless router in my son's room on the second floor and connect it with a Cat5e ethernet cable to the Superhub on the ground floor. This way, I will have a wired connection on the ground floor for my desktop computer, my son will have a wired connection for his PS3 and laptop and his own wireless network.
I just want to know if this will work with an ordinary cable wireless router? Or do I need some sort of special access point? If this will work, do I connect the cable from the Superhub to the WAN port of the old router, or to one of the four other ethernet ports?

I want to go from my asus rt-n66u router wirelessly to another device that I can plug an ethernet cord from a desktop computer. I work on computers and my workstation cannot be close to my router. Instead of installing a wireless adapter everytime I work on a computer, I want something that I can plug an ethernet cord into that will connect wirelessly to my router. I just want to get an internet connection to my work computers without having to run an ethernet cord across my front room. I have read so much about bridging and access points but can't really figure out what would be best or what my router is capable of. I have tried in WDS mode and couldn't get to work with another router I have and also read it cuts you bandwidth and also forces you to use WEP securit

I have a DIR-655 router downstairs on one side of my home. Upstairs on other side of my home wireless signal is really hit and miss. I do have ethernet in the area of my home where I am wanting to extend the signal. Is there a device I can plug into the ethernet to extend my wireless signal without creating a new network or ssid?

I have an existing network in a 300 year old structure. There is a base router from which there are 3 wired (ethernet) lines to parts of the structure. Due to the structure itself (near 2 ft thick walls - masonry) the wireless from the base router reaches only a short distance. I would like to "extend" the wireless reach using those 3 existing runs. So - can I add 3 more routers or should I go with Wireless Access Points or what else would work?

Sending WiFi signal about 1/4 mile from my home to where my daughter lives so she can use her Samsung Galaxy2 Tablet on WiFi.There are homes, condos and trees in between us, so it is not a clear path.So far this is what I have done.I am using a modem and a Netgear WNR834B Wireless N Router.I connected a Hawkins Laptop Extender (HWREN Wireless 150N Mini Extender * single antenna outlet) into the router and connected a WiFi cable from the Hawkins to my tower outside above my roof and have attached a 10 dbi gain Trendnet antenna (omnidirectional) to the cable.But still the WiFi signal doesn't seem to be very strong at all when I test with my phone.And obviously, my daughters tablet does not see my router when she has her tablet search for WiFi.I also tried a 14dbi WIfi ASUS directional antenna and basically came up with the same outcome... she could not see the WiFi signal..My daughter lives in a condo and is not capable or allowed to install any outside antenna system whatsoever.

I am trying to setup an E3000 router and extending the network with a WAP4410N acting as a repeater.
I am faced with the same problem and it looks like it all comes down to this: without the WAP4410N having a physical connection to the LAN, it will not connect to the E3000 as a wireless client whether it's configured in AP mode: WDS Repeater or in client/repeater.
I've tested with various permutations that have been explored in the various discussions: matching channels/bandsmatching and non-matching SSIDs matching security settings using site survey to set the mac address of the E3000 (ensuring it's the MAC of the 2.4Ghz wireless)setting a static IP on the WAP4410Nensuring both devices are on the same subnet. Any way to be truly successful with this pair up of E3000 & WAP4410N or is it simply a technical product limitation?

I have a Linksys e3000 and a Linksys WRT120NVery simple setup. the 3000 is in my office. There is a cable that goes from this routerto the living room across the house, it is just laying there. Since I cannot get a wireless signal into that room,I would like, using the cable that is hanging there to make use of the other linksys and provide a wireless signal to the living room, all under the same network. In essence, extending the wireless network using the cable in the living room that is connected to the main router in my office.My question is, without touching the master router, how would I set the 2nd router in the living room up?I understand that DHCP on the 2nd router needs to be turned off, and a channel selected so that it does not overlap. Same SSID, Sam WPA2 key.Or would there be a device better suited for this?I do not want to extend the 2 rooms wirelessly I want to use the cable, then use the wireless in the living room for wireless devices etc.

I am trying to extend the wireless network at our church beyond a firewall to another area of the builing. We have a cat 5 cable run through the firewall to the other side. I have a brand new Linksys E2500 router. Can I assign an IP to this router and connect it's WAN "Internet" port to one of the ports on the main router that is connected to the cable modem and use it to extend our network?

I've recently purchased an E4200, and while it works great, I'd like to use my Apple Airport Extreme (2nd generation) to extend my network to another part of the house that doesn't get as great of a signal. I've become very frustrated trying to accomplish it, and I'm not sure if the problem is more from the Linksys end, the Airport end, or if it's just me.

Cisco 1240AG converting to WEP to WPA
Access Point Model: Cisco 1240AG
System Software Filename: c1240-k9w7-tar.123-7.JA5
System Software Version: 12.3(7)JA5
Bootloader Version: 12.3(7)JA1
Access Point Model: Cisco 1131AG
Software: Cisco Aironet Desktop Utility 2.1.02
After converting encryption from WEP to WPA in a Cisco 1240AG in personal mode with an SSID name of example1 and Cisco 1131AG access point in personal mode with an ssid of example2; both with the same wpa passphrase, I created a new profile on the Cisco Aironet Desktop Utility with a new profile name as well as a WPA passphrase, but the desktop utility will only connect to the access point if one network name, example1 or example2, is entered.

I'm looking at creating WLANs using standalone APs for the first time. I know this can all be done with trivially a controller, but this project can't stretch to that...Can I use MAC filtering on standalone APs to restrict which clients associate?I think these will be 1240AG devices but I assume the answer is the same for all models?Can I mix MAC filtering with WEP/WPA? And use MAC filtering without encryption?

I have a 1240Ag. Earlier I loaded a startup config from a backup. The AP came back up - I can SSH into it, but when I try to access the web management page it says "IE cannot load the webpage".

For 2 year now we have been running aironet 1240ag access points throught our warehouse. We use a telnet session on our handheld scanners to connect to our database on the main server.This last week our scanners started getting dropped from the access points serveral times throught the day and often would continue to get dropped at 1 minute intervals for several minutes at a time. This appears to be happening on all of our access points and is affecting all of our scanners but not at the same time.Each time a clinet is dropped we get the following event log on the AP.
Sep 29 11:57:14.807 -0500 Warning Packet to client 0c77.1a3a.6ff7 reached max retries, removing the client

how is the IP configuration for this Fast Ethernet F0.
This is because usually we only assign IP to the BVI interface. Is it after that, the Fast Ethernet F0 automatically also be assigned the same IP?
As such, when goto the Fast Ethernet F0 by CLI, by using no shut then this will Enable the Fast Ethernet Port?

I am setting and configure the Cisco AP 1240AG with 5GHz External Antenna extension. The whole product is called iWap. The problem now is that the wireless signal amplitude only can reach 3 bars instaed of ful 5 bars.
Few questions I have for this setup and configuration :
1. What is the default or original frequency of antenna of Cisco AP1240AG? Can a 5GHz antenna work with the AP 1240AG whereby it is run with 802.11a and 802.11g?
2. If 5GHz antenna can work with 802.11a or 802.11g, what is the setting or configuration needed to be done at the Cisco 1240AG? Or, no setting or configuration needed because it will automatically work by default?

We are using an Aironet 1240AG series wireless AP here to connect handheld scanners. They work fine on WPA. However, when we switch to WPA2, they often lose connection. We have tested on 802.11g and a bands, with various encryption types (TKIP, AES, TKIP/AES). Also, how can I update the outdated firmware without signing up for a service contract?

They are 8 APs Cisco 1240AG installed inside our warehouse, on the other hand we had some places with poor signal level -82dbm so we put two router linksys wrt54g.
The Cisco APs have 2.2dbi omnidirec antennas and they are configured with the same SSID on different channels (1,6,11) and max tx, rx (100mw).
When we check the signal level we realized that we have more signal from the linksy than the Cisco?

I work as Network administrator in a building products plant at Poland. We had core switch HP Procurve 6200yl with 5 vlans, and 11 Aironet 1240AG Access points without controller. I have a problem with create 2 wi-fi VLANs on the Cisco AP's and linked it with HP switch.
VLANs on the switch:
1 - Default (for office sutff) - working great,
2 - Production (for production stuff) - working great,
3 - Inter (for Router's) - working great,
4 - WMS - i need configure it as wireless,
5 - WiFi with Radius - i need configure it as wireless.VLANS on the Access Points:
4 - WMS - for warehouse terminals - WPA2,
5 - WiFi for office stuff with Radius.
I'm easily able to get it running a single SSID (non-VLAN) network and confirm that I can use that network fine. However, I need to set up these 2 VLANs. I can connect to it via telnet if that'll let me program it faster.

I am wanting to buy an access point to extend my range on my home network. I think i've used one AP before and if i remember correctly, after i plugged it into my main rounter and configured it, i unplugged the ethernet from it and moved it to somewhere else in the house. But i can't remember for sure if this is how it works or do i have to have an ethernet cable running to it at all times?

I am an IT professional that is installing my first extended range wireless AP in my companies warehouse. I am very excited!
Now I have set up many a linksys and repeater wireless networks, so when I was looking into the Aironet 1240AG I thought ?No Problem!?
And at first, it is not!
I have the AP and antenna set up here in my office before I take it out and mount it in the warehouse. And I can get connected to it, no security for now, no filters, I just want to connect and make it work.
I stay connected for maybe 3 minutes, I can get to the internet, I can ping all my servers. Full connectivity. But then for no reason the connection fails and I cannot reconnect.
The error I get in the log is
Interface Dot11Radio0, Deauthenticating Station 0006.2510.bbe3 Reason: Previous authentication no longer valid
So strange! So I have reset the AP to factory defaults and then set the SSID, and I can connect, again for a second, then nothing.
I have tried with multiple wireless cards, even laptops. Thinking maybe the problem was on the computer side.

I have a Cisco Aironet 1240AG Access Point and I am trying to setup a guest network that is secure and limited in bandwidth utilization. I see an option under security > SSID Manager on the web interface to select an interface of Radio0-802.11G, Radio1-802.11A or both. Can I put the guest network on the Radio1-802.11A and make it more secure/bandwidth limited or does this option not matter?

I have family members living in two houses side by side.One house has the cable modem and a wireless router, and the other doesn't.The signal in one house isn't strong enough to reach the 2nd, so I'm thinking of running cat 5 from the wireless router lan port to the other house.

have a home network setup that works completely fine everywhere in the house except one room. That room happens to be my son's room that has his Xbox 360 in it. He wants to play online but I cant get a signal back in there and if I do it is extremely weak. I have a linksys E2500 router connected to my cable modem that is wired ot one computer and then my 2 laptops connect to the wireless from that router. The Playstation 3 that is about 15 feet away works fine as well. All our ipods and iPhones work well too. It is only his bedroom where we run into trouble with any of these devices. I actually just upgraded to the E2500 about 2 months ago, so I have a Motorola WR850G sitting around. Can I use this closer to his room to lengthen my signal or how can I proceed to get him a better signal

We've got an SA520W that's performing nicely, but we need to extend our wireless coverage to a new area of the building (we can get a network cable there). What would be our best option? Just a second SA520W, or are there are APs we should look at?
