2.4Ghz and 5Ghz Sync

Does anybody know if there is an advantage in syncing the two bands

I presume by synching you mean both frequencies using the same SSid.
If you have a wireless device that is capable of dual-band it will automatically select the most suitable frequency. If you are close to your homehub it is likely to automatically select the 5Ghz range as this will give you a faster smoother connection with less interference. The disadvantage of using the 5Ghz is it's not as effective through walls and over distance. So, for example, if you try to connect wirelessly from the garden, the BT Home Hub 4 smart router is likely to automatically switch over to the 2.4Ghz range which covers greater distances.
If you have a separate SSid for the frequencies you effectively have two separate networks so your devices would not automatically jump to the best frequency.

Are both 2.4GHz and 5GHz networks enabled by default?

I have a TC 4th Gen and, according to the box it has both 2.4Ghz and 5GHz networks. Simultaneously.
Questions: Is this so? What makes a device choose 2.4GHz or 5GHz?
Thanks!
Fernando

Is this so?
Yes. Both bands use the same wireless network name.
What makes a device choose 2.4GHz or 5GHz?
Assuming that a wireless device is capable of connecting to a 5 GHz band (an iPhone cannot), it will "look" at both bands and choose the band with the best quality...which is a combination of signal strength and low noise.
5 GHz signals are not as strong as 2.4 GHz signals, so if the computer is a few rooms away from the router, it likely will connect to the 2.4 GHz band because those signals penetrate and travel through obstructions more effectively. 5 GHz signals are absorbed more quickly by any obstructions.
You can "force" a device to only connect to the 5 GHz band by assigning a different name to that band using Wireless Network Options and then "point" the computer at that network. But, that is no guarantee that this will be a better connection. It might be inferior to the 2.4 GHz signal.
For most users, it is probably best to leave the router in its default settings and allow the wireless devices to choose and connect to the band with best quality. After all, isn't that what you want?
Want to know which band your Mac is connected to at any given time? Hold down the option key on your Mac while you click on the fan shaped AirPort icon at the top of the screen and look at the Channel info.

E2500 2.4GHz and 5GHz Channels

Hi guys / gals,
I've recently purchased the E2500, done the setup but am facing some issues.
I'm unable to see the 5GHz channel SSID, I can only see the 2.4GHz channel SSID.
Have tested all the laptops and devices at home and all can't see the 5GHz channel.
The list of devices are:
a) iPhone 3GS
b) iPhone 4G
c) iPhone 4GS (some sites says it doesn't support, some says it does, I'm confused as a result)
d) Samsung laptop
e) Dell laptop
f) Momo11 Little Bird Edition tablet (Made in China [MIC])
g) No name MIC tablet
Secondly, is there any tips / tricks to tweak the modem to increase the internet speed?
Appreciate whatever assistance you could provide.
Thanks in advance.
Daryll

First, with the above devices you must have a 5Ghz capable wireless adapter in order to see a 5Ghz signal. Verify which devices above have a 5Ghz adapter installed. This means it must be 802.11 a/b/g/n cabable, not just b/g/n.

Different ping/latency with 2.4ghz and 5ghz

Today i installed my new TC, last model.
I usually had: 2.4ghz band, ping 4ms, download rate 40Mbps.
Now i have a very absurd situation
With Safari
if i use the 2.4 ghz--> ping 4ms, download rate 40Mbps
if i use the 5 ghz--> ping 32ms, download rate 96Mbps
With Chrome
if i use the 2.4 ghz--> ping 4ms, download rate 40Mbps
if i use the 5 ghz--> ping 4ms, download rate 96Mbps
How is it possible?!?!?!?!?!?!?

Trying to connect to BOTH 2.4GHz and 5GHz bands on WRT610N simultaneously!??!?

Hi everyone,
Alright, so I got this cool router, configured it, with the exception of what the 610N's unique feature of connecting to both the 2.4 and 5 GHz bands for a total of 450Mbps??
I'm running Vista Ultimate 64-bit, and cannot seem to find as to where to configure it to take advantage of the higher bandwidth!??
Can someone please help regarding this? Am I really going to see a dramatic difference.
Other than that, I love my 610N!
Thanks very much!

I see...I have the Atheros 11a/b/g/n AR5008X (XSPAN) mini-PCIe wireless adapter installed in my Thinkpad.
What configuratio(s?) do I need to make either on the router, the card, or both??
Are you able to do this, and will it make a noticeable difference?
Thanks!! Linksys ROCKS!

WLC with 2 WLANs, 1 voice @ 2.4GHz and 1 data @ 5GHz 802.11n

I have a WLC 4400 series and am using 1142n APs. Am planning on adding Wireless IP Phones such as 7921/7925 as well as a couple 9971's. Is it possible to have 2 WLANs, one to connect the voice endpoints to running @ 2.4GHz and another WLAN with a different SSID for data clients @ 5GHz? All data clients have 802.11n NICs and can operate @ 5GHz. I have enough APs so that the lessened range of 5GHz won't pose any issues. Ideally I'd like to see connection rates in the 240mbps-300mbps range on the data clients with data throughput rates of 100mbps+ (I don't think this ought to be an issue, I'm aware that wireless is half-duplex and that connection rates do not necessarily indicate actual throughput rates). I am also NOT a wireless expert. I'm still fairly new to working with the WLC and the managed APs as such.
The reason for 2.4GHz and 5GHz simultaneously is that the voice endpoints are all 2.4GHz radios, I believe 802.11b/g. I also want to keep voice clients separate. This way, I believe I can optimize one WLAN for data clients without having them "suffer" so to speak by having to operate at a lower level as the voice clients. Also, I want the voice separate for quality there (separate voice VLAN). If I am correct, 802.11n data rates can also be achieved @ 2.4GHz, but only using the 20MHz as opposed to 40MHz width. So I'd like one WLAN to be 2.4GHz, 20MHz (voice) and the other WLAN 5GHz, 40MHz (data).
I'd like to hav both WLANs broadcasted from all the APs simultaneously. Am I correct that such a configuration is possible with the WLC 4400 series and Aironet 1142n APs? WLC is running 7.0.240 btw, current stable. I'm also starting with a clean config on the WLC. All DHCP will be handled by an external DHCP server also. Thank you very much for any suggestions/guidance on this. Your thoughts are greatly appreciated!
I'll be happ to supply any config information to assist with this, just let me know what is desired/useful.

Thank you for your prompt response. I only have 1 WLC, it is a 4402-50. I believe that 7.0.240 is the most current release for that model. I think anything higher I need to go to the WLC5508 (or vWLC?)
Also, I wasn't aware that the 7921/25 were 5GHz, since they are both 802.11g. Thank you for the information.
If I understand you correctly, I'm best creating 2 WLANs, but both at 5.0GHz for both data and voice?
Also, sorry to confuse the issue further, but I was thinking about this after writing the original post, I'd like to also have a "guest" WLAN that supports both 2.4GHz and 5.0GHz for maximum client compatibility (as I have no way of knowing what tpye of WLAN NIC would be in guest devices). Am I correct in assuming that I would create a separate WLAN for all these, including a separate SSID.
The part that is confusing me some now is the "AP Groups". Do I leave a single "Default-group" and create multiple WLANs with that. If I'm correct, this way I can push the WLANs and SSIDs out through all the WAPs in that group. I want these WLANs to be available from any AP in the organization, not have some APs for one WLAN, other APs for another WLAN, etc.

Can I extend both a 2.4Ghz and a 5Ghz wireless network at the same time with a second Timecapsule / Extreme ?

Can I extend both a 2.4Ghz and a 5Ghz wireless network coming from a Timecapsule with a second Timecapsule / Extreme at the same time?

I am currently extending my 5Ghz network via an Express without any problems, but the Express can only extend either / or. I just want full coverage for both networks in the whole house.
If you can extend 5 GHz now with an AirPort Express and get satisfactory results, then the AirPort Extreme will work to extend both the 2.4 GHz and 5 GHz bands in the same location.
However, your computer is going to connect to the band with the strongest signal, so it may....or may not....connect to 5 GHz given a choice of two signals.

Airport Express only broadcasts either 2.4ghz OR 5ghz at any one time?

Hi folks...here's hoping someone can help. I've searched high and low, but have not been able to find the answer.
I just got an Airport Express and successfully set it up to extend my existing network (from an Airport Extreme Base Station). However, it seems to be only extending the 2.4GHz signal. When I look at the set-up in Airport Utility, it seems that I would have to select either the 2.4GHz OR the 5GHz...it can't seem to broadcast both signals (unlike the Airport Extreme)
Does the airport express only broadcast either 2.4ghz OR 5ghz at any one time?

Does the airport express only broadcast either 2.4ghz OR 5ghz at any one time?
Yes. If you have the AirPort Express set to "extend a wireless network", it will extend either the 2.4 GHz or 5 GHz band, but not both. The AirPort Express is dual band in a sense that it can handle 2.4 GHz or 5 GHz signals. But, it can't do this simultaneously.
The Express extends the band that it "sees" with the strongest signal, which will be the 2.4 GHz band in most cases because 5 GHz signals are weaker and do not penetrate obstructions or travel over distance as well as 2.4 GHz signals.
If you want to extend both the 2.4 GHz and 5 GHz bands, you'll need another AirPort Express, or a simultaneous dual band AirPort Extreme would do the trick as well.

AP541N-E-K9 2.4Ghz and 5 Ghz at same time

Hello Everyone,
I'd like to set up a 2.4Ghz and a 5Ghz SSID at the same time, using one Cisco AP541N-E-K9. But I can't figure out any way to do so. Is there a possible way?
Kind Regards

Hello Christoph,
The device only has one wireless radio. Its only possible to either have 2.4ghz or 5ghz being broadcast but not both at the same time.
Thanks,

Qosmio x770-136 Dual band wifi 2.4 and 5ghz - how to switch between them?

Hi Guys,
getting a new router netgear dual band N900, and it supports multi 2.4-5ghz wifi,
my question is how to i set my qosmio up at 5ghz?
thanks for any replies

Hi
Found this details on Intel page:
http://www.intel.com/content/www/us/en/wireless-products/wifi-link-5100-brief.html
It seems that Intel 5100 WLan card supports 802.11 A/B/G and N so it will operates at 2.4GHz and 5.0GHz.
The Wlan card is also available in miniPCIe format so it should be possible to insert this into the WLan slot on the mobo.but question is if the BIOS would supports this
To be honest I dont know there are no info about that and according to some users here in the forum, it could be possible that notebook would not power up using new WLan card.

Virgin Superhub settings to allow Airport Extreme to broadcast at 2.4 and 5Ghz

I have a 120Mb Virgin Superhub (SH) installed in my home but its wireless performance is terrible. The SH router can work in wireless or modem mode at 2.4Ghz or 5Ghz but not simultaneously. I'm therefore going to place my SH in modem mode and connect up my Airport Extreme which can broadcast at 2.4 and 5Ghz simultaneously which will allow me to use all my tech at their best frequencies.
My query is what do I set my SH to? 2.4Ghz or 5Ghz to enable my Airport Express to broadcast both frequencies. Hope you can help.

Hi - if you configure the SH to be just a modem then all it should be doing is providing internet to the Extreme - the Extreme can be used with almost any cable or DSL modem without having to touch the modem so 2.4Ghz or 5Ghz would have nothing to do with the dual band capabilities of the Extreme - I would check with the SH manufacturer or ISP to make sure that this is the case - since you already have the Extreme, it won't hurt to try it.

I have a dual band router. How can I tell if my iPad is using 2.4Ghz or 5Ghz.

I have a dual band router. How can I tell if my iPad is using 2.4Ghz or 5Ghz. I want to try and manage all the devices in the house over our WLAN. Thanks. Nik

I'm not really sure there is a way to tell, it certainly doesn't seem to be something you can set within the iPad so I'd assume that if a 5Ghz frequency is available it would use that, otherwise it would default to using a 2.4Ghz frequency instead. I'd also assume from having a 5Ghz router myself that there would be some sort of light on your router which will flash on/off when data is recieved so if iPad is your only 5Ghz device and it's sending/receiving data then this light should flash on your router.

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine until I deleted an app in error. When I downloaded it from iTunes, my account is no longer recognized by the app's host servers. Can I go back and re-sync one app from my old phone?

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine. Yesterday I deleted an app in error. When I downloaded the software it from iTunes ( did this many times on the old 3GS), my account is no longer recognized by the app's host servers (Playtika), even though it did after the initial conversion. Can I go back and re-sync just one app from my old phone?

Try deleting what is called the iPod Photo Cache.
http://support.apple.com/kb/TS1314

When I plug in my iPod and it syncs it says that a bunch of my apps cannot be loaded because my iPod does not have the latest software to support them, but I have done all of the iPod software updates and the same apps were working fine just weeks ago...?

I plug in my iPod to charge from my computer and it syncs with my iTunes, but I've been getting a message that a list of 13 of my apps cannot be loaded onto my iPod because it doesn't have the latest software to support them. I have done all the software updates for my iPod and iTunes says it is completed up-to-date. Do I need to delete the apps and redownload them or what?
Any help is appreciated! Thanks.

ok well like lllaass said, most apps require 4.3 or later iOS software. chances are since the apps worked before, the apps themselves got updated and will no longer work with your software version.
