Can a 1252 AP support 2 * 5Ghz Radio Modules

Any ideas if the 1252 units can support two 5Ghz Radio modules, or must they run with one 2.4Ghz and one 5 Ghz?

As much as I know - no.

Disable 5Ghz Radio module in LAP1252AG

Hello,
I have a LAP1252AG-E-K9 managed by a WLC embedded in a Catalyst3750G. My question is the following: how can I disable the 5GHz radio module using the WLC (I desire leave only the 2.4GHz module). In addition : in case I put in the LAP only 3 2.4Ghz antennas the 5GHz module is automatically disable?
Thank you, Marco

I haven't tested this but I beleive I've read that just disabling the radio via controller doesn't actually solve power problems- if you're trying to get full power to one 2.4 radio using just 15.4 watts, I believe you do have to physically uninstall the other radio.
If anyone can confirm otherwise, please post.

802.11n: How can I force a wireless adapter to primarily associate to a 5Ghz radio and not to the 2.4Ghz one?

Hi experts,
I am playing with a Cisco 1142 AP. I have same SSID configured on both dot0 and dot1 interfaces. I have a test laptop and it has a Linksys dual-band wireless adapter. However the card always try to associate on the 2.4GHz. It will only associate with the 5GHz radio when I shut down the dot 0 interface. The laptop is running Windows XP SP3 and I'm using the windows wireless Zero configuration to configure the wireless. The following is the AP's configuration:
dot11 ssid Guest-Wireless
authentication open
guest-mode
interface Dot11Radio0
no ip address
no ip route-cache
ssid Guest-Wireless
antenna gain 0
channel 2412
station-role root
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 port-protected
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
interface Dot11Radio1
no ip address
no ip route-cache
ssid Guest-Wireless
antenna gain 0
dfs band 3 block
channel dfs
station-role root
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 port-protected
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
Is it something I can control through the AP or it's the laptop/wireless adapter's own behavior so I either need a new card or update it with a new firmware?
Thanks!

Leolaohoo,
Thanks for quick reply! My laptop is just next to the AP. There is nothing but air between the laptop and the AP.
I actually did speed tests on both 2.4 and 5 (with 2.4 disabled of course) and I got pretty much the same result: 46Mbps MAX. I don't know if it's the linksys n card is limiting the capacity of the AP. But for now I just want it to jump on 5GHz instead of 2.4GHz...
Thanks,

My iPad does not support flash player. What can I do to listen to Finnish radio on the iPad?

Help! How can I listen to my beloved Finnish radio on this new fangled iPad? To listen to it I require flash player. Any ideas?

For general internet radio listening I recommend TuneIn Radio, either the free or paid Pro version.
If by Finnish radio you mean Yle they have an app available, they even direct you to it when you first surf to their website.

WRT610N - Cannot Get 5GHz Radio to Work

I have a WRT610N (firmware 1.00.00 B18), and I cannot get the 5GHz wireless radio to work under any mode (Mixed, A-Only, or N-Only). 2.4GHz radio works fine on all modes.
As far as I can tell, the 5GHz radio isn't even coming online. Settings are:
Wireless Configuration: Manual
5GHz Wireless Settings:
Network Mode: Mixed / A-Only / N-Only *
SSID: linksys-test
Radio Band: Auto / Standard / Wide **
Wide Channel: Auto (DFS) ***
Standard Channel: Auto (DFS) ***
SSID Broadcast: Enabled
2.4GHz Wireless Settings (Disabled)
* Tried all different network modes
** Tried standard for .11a and both standard and wide for .11n
*** Tried leaving on Auto, as well as forcing channels to 38, 46, 151, 159 (for wide) and 36, 40, 44, 149, 153 (for standard)
Tried with several different clients (MacBook Pro, various Dell and Lenovo laptop PCs), and none of them can detect anything at 5GHz from the WRT610N. All the clients are known to be working, as they are able to see other 802.11a and 802.11n (5GHz) wireless networks on other routers I'm testing (Apple Airport Extreme and D-Link Xtreme-N).
Could it be I have a broken WRT610N? Or is there some other setting needed to activate the 5GHz radio?
Thanks.

Why do you think that your 5GHz isn't coming online? Not all devices can connect to the 5GHz BAND. So if your trying to SEARCH for your 5GHz network and it's not showing up in the list along with your 2.4GHz network then perhaps your device doesn't support the 5GHz band.
For example, on a PS3 if you try to search for a wireless network, a PS3 will only find the 2.4GHz network because the card inside the PS3 doesn't support the 5GHz band.

Does the iPhone 4S support the 5GHz band?

While the iPhone 4 supported 803.11(n), it did so only on the 2.4GHz band. I can't find any information about this for the 4S. Does anyone know if it supports the 5Ghz band?
Sorry....I asked too quickly. The answer is NO. See http://www.apple.com/iphone/specs.html

802.11a/b/g/n Wi-Fi (802.11n 2.4GHz and 5GHz).
No, it does not state that.
The 4S does not have the 5GHz radio.

Which Aironet 1252 radio module(s)

I was going to use an Aironet 1252 access point to set up a wireless network and was wondering which radio module (or modules) to get. I have no need for backwards compatibility, so it seems that for best performance I should go with a pure 802.11n network. In order to achieve that goal, is one radio module sufficient? And which band would be best? Or is there any advantage (or disadvantage to getting both the 2.4 GHz radio module (AIR-RM1252G-A-K9) and the 5 GHz one (AIR-RM1252A-A-K9)?
Any and all suggestions or thoughts are greatly appreciated. Oh, and if you need any other information about my setup please feel free to ask.
Thanks,
Paul

fella5 is right. You've just mentioned the need for backward compatibility therefore both A/B/G modules is OK.
Are you going to be using a Wireles LAN Controller (WLC)?
The reason why I'm asking is because the 1252 AP, in order to get both RM to work, you need at least 19.0 watts of power. This can only be achieved using either a enhanced PoE switch (such as the 3560-E/3750-E) or a power injector.
The latest code of the WLC (firmware 5.2) will upgrade the AVR of both the radio modules of the 1250 to be able to operate at 15.4 watts of power. Here's the catch though: The new WLC code will allow the 1252 to operate both radios BUT the power output (or signal strength) is curtailed.
However, do you look the 1140 series AP. This model will operate at 15.4 watts of power, full signal strength but the range is not as far as the 1250.
The 1140 (like it's other brother, 1130) was designed for office use: lots of walls, partitions and corners. The 1250 is designed for industrial use: wide-open space, environmental protection (thus the armoured-tank look-feel-weight).
Hope this helps.

I have a G5 and iBook with PowerPC/iTunes 10....just recently I can't bring up the preset Internet radio on either one. Is this a glitch, or have they been permanently disabled for older versions of iTunes?

I should have posted this for you a while ago. My apologies for not doing it sooner. This was passed on to me by another user R C-R
He deserves the credit for this workaround. This is his post from an area in the forum where you have to be level 6 or higher in which to participate.
I am getting the same (global) error using iTunes 10.3.1 on a 2008 MacBook running 10.6.8.
A really, really awkward workaround that works for me (for now) is if you have the URL of the Internet radio server you can go to Advanced > Open Stream... (in iTunes 10.x) or type command + U, enter it there & click OK. The station should play fine in 10.x.
You can get the URL from any version of iTunes that still supports the "radio tuning service" (which I gather is an Apple server thing Apple is no longer supporting for 10.x). Play the station normally from the newer version & type command + I to open the info window. At the bottom of the "Summary" tab you will see the URL. (Annoyingly, you can't copy the text so you will have to write it down.)
Once you have that, you can play the station in 10.x & add it to a playlist for future use.
To check this out, maybe try http://198.27.80.37/stream/mbarsott.pls -- it is a European Jazz station that works fine for me with iTunes 10.3.1.
This workaround does work, but is a bit cumbersome. I'm still holding out hope that it is just a glitch.

Only Apple Account Security could help at this point. You can try calling Apple Support in Canada - you'll have to find one of the several ways, such as Skype, to call an 800 number from outside of the relevant country - and ask for Account Security and see if they can help. Or you can find a friend who speaks Chinese and ask them to help you talk to Apple Support in China. There are really no other options that I know of.
Note, by the way, that these are user-to-user support forums. You aren't speaking with Apple when you post here.
Regards.

I can not longer send email from my .me email. in outlook 2010 on my PC. I can still recieve emails fine. I have not changed my settings at all. I have however tried all the settings i can find on the support pages. PLEASE HELP

I can still receive icloud ( ME email address) emails fine. I have not changed my settings at all. I have however tried all the settings I can find on the support pages. PLEASE HELP. Nothing has changed. This suddenly just started happening around a month ago. To frustrate me apple does not seem to have a support email or any method to contact them with this issue to do with their email product. I have spent ages going through the apple support sites and I keep getting asked for an apple product to mark it against. I have no apple product as I am using a PC but I am accessing and using their email product. Is there even a phone number I can call? Surely there is a support area for their Email server issues. Can anyone help? It is driving me mad and causing me major issues. My outlook is Outlook 2010 on a windows 8 PC. As I have said it worked fine then one day decided to stop sending emails.
Thanks for your help.

Can my Macbook Pro support dual boot and Secret World

Hi
My MacBook Pro has the following specs
Processor 2.8 GHz Intel Core i7
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
Software Mac OS X Lion 10.7.4 (11E53)
I was wondering if it can first of all, support dual boot, because I would like to play a Windows based MMORPG. And I was wondering if there are risks involved? I'm also worried because I like Mac's secure delete trash function and won't having a Windows platform affect that?
Furthermore, can it support playing Secret World with such specs?
Secret World is an MMORPG I'm not sure what the minimum requirements are.. It doesn't say, but anyone has a guess?
-EDIT
OS:      Windows XP (SP 1)/Vista (SP 1)/Windows 7 (SP 1)
PROCESSOR:      2.6 GHZ Intel Core 2 Duo or equivalent AMD CPU
MEMORY: At least 2GB RAM for Windows XP / 3GB RAM for Windows Vista and Windows 7 *
VIDEO CARD:     nVidia 8800 series 512 VRAM or better/Radeon HD3850 512MB or better
DIRECTX: DirectX 9.0c Compatible

If you have an MBP with a Core 2 Duo processor and a clock speed of 2.16 or 2.33 GHz, your max is 3 GB. If you have a 2.2, 2.4, 2.5 or 2.6 GHz clock speed your max is 4 GB.
Check Apple menu > About this Mac for processor type and speed.
I can tell you what you should see - C2D at 2.16 or 2.33 GHz. Those machines have a 3 GB max stated by Apple, but will actually use ~3.2 GB if you have 2 x 2 GB installed, and you get the (marginal) benefit of having a matched pair. In that case, it's also 'normal' for About this Mac to show 4 GB even though the memory controller can only access a little over 3 GB.

Can the AirPort Extreme support more than one printer at a time?

can the AirPort Extreme support more than one USB printer at a time if it is connected to a USB Hub?

can the AirPort Extreme support more than one USB printer at a time if it is connected to a USB Hub?
Yes.....IF.....you use a powered USB hub.
I have had 3 printers connected at the same time in the past and assume that more would work as long you have a powered hub to support the number of ports that you need.

IWeb is not working for sending podcasts to iTunes, so I need a new web building tool. What is the closest thing to iWeb that I can use, which also supports podcasts?

iWeb is not working for sending podcasts to iTunes, so I need a new web building tool. What is the closest thing to iWeb that I can use, which also supports podcasts?

There's no reason you can't go on using iWeb for this - with iWeb '08 you have to publish to a local folder (i.e. on your Mac) and then upload the contents of the folder (not the folder itself) to your hosting service: and you have to make sure you enter the new URL in the Publish information or the feed won't work properly; this done, an iWeb podcast should work fine.
Of course there is still the problem that iWeb is not supported and sooner or later a system upgrade may break it. You could look at RapidWeaver: you can make podcasts with that, though the last time I looked into that - which was admittedly some time back - I didn't feel it was ideal for this. There are lots of other podcast creation programs or services around. WordPress is OK but it may be a bit of a steep learning curve: Libsyn is an online service that seems to work reliably. Blogger writes messy feeds but does usually work. Podcast Maker used to work well - I used it myself a few years back - but it rather looks as if it's gone moribund and it may not be reliable with Lion/Mountain Lion, so you would want to check into that.
