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.

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.

Similar Messages

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.

2.4ghz and 5ghz

HI,
i have cisco AP 1242 AG with 2.4ghz and 5ghz frequency.
Can anyone tell me what is the difference and also let me know whether we can use 5ghz frequency according to indian RF regulation.

Linksys EA3500 and 5gHz channels

Hello.
I bought linksys EA3500 in Russia 2 days ago and i can see only 4 5GHz channels - 36, 40, 44 and 48
But i want to choose channel from 149 till 165, which is legal in Russia.
How can I get this channels to choose?

What's the firmware version of your router, XvaN? Set the 5 GHz Channel Width to 80 MHz, you will then be able to select channels 149 till 165.

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.

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.

Issue accessing 5GHZ channel WRT610N to uverse

Not sure if anyone has encountered this issue, I connected my dual band WRT610N to uverse router. I disabled the wireless feature on the Att 3801hgv router and now use linkys router. Both 2.4GHz and 5GHz network can be seen however I am only able to connect 2.4Ghz channel. see setting below i am using. Hope someone can help.

Make sure that there's no IP address conflict between the two routers. If you cascade the routers and set the WRT610N as an access point then you need to disable the DHCP server of the Linksys router. You may use Linksys KB article 3733 to guide you.

Connect MacbookPro and AirPort Extreme via 5Ghz channel

Hi.
I have three Apple devices:
- Macbook Pro 13" 2012 year (802.11n wi-fi standart)
- iPad mini with Retina 2013 year (802.11n wi-fi standart)
- Airport Extreme 2013 year (with support 802.11ac wi-fi standart)
By default, a macbook device connected to the channel 2.4Ghz. Connection speed is set 217 Mbit/sec. If you divide the channels 5Ghz and 2.4Ghz, then the connection speed to 450 Mbit/sec on channel 5Ghz.
How to configure AirPort Extreme when macbook and iPad was connected to the AirPort using 5Ghz channel by default?

Bob, how can you comment on these results?

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.

5GHz channels no longer available after upgrading to 10.7.3

I'm currently using Late-2009 iMac and for some reason after upgrade to 10.7.3 I couldn't connect to any 5GHz network at all. In the System Profiles, Wi-Fi menu now says:

which now lacks the upper channels previously supported (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 34, 36, 38, 40, 42, 44, 46, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165); I wonder if this is intentional, if so, for whatever reason did Apple decided to disable 5GHz support for this particular build (which previously worked flawlessly)

Interesting. If you can still connect via wired (or 2.4GHz wireless), I would download the 10.7.3 combo update from apple support and reapply it. It appears the driver and family did not fully install with the update.
You can get the update here:

WRT600N Network Dropouts on 5Ghz Channel with WPA-2

I've got a WRT600N using WPA-2 Personal on the 5Ghz channel. Whenever I try to upload something from my machine to a NAS attached by ethernet to the device I lose the wireless connection. This doesn't happen if I turn encryption off, or if I'm uploading to something on the Net, only a device connected to the ethernet port. It doesn't matter whether I use zero config or Intel Proset. It doesn't seem to matter whether it's the NAS or any other device connected to ethernet port. The same problem happens with every variation of WPA. It's fine if I connect to the 2.4Ghz channel.
I've upgraded to the lastest firmware for the router (1.01.35 build 5) and NAS as well as the latest driver for the intel wireless card. I'm using all the default settings on all the devices.
Does anyone have any ideas why this might be happening with WPA, other settings I could try, anything that might help.

I just used the download - this is on a Vista 32 machine but drivers are available for Vista 64 - http://www.linksys.com/servlet/Satellite?c=L_CASupport_C2&childpagename=US%2FLayout&cid=117523973773....
It's been running fine for the past few months although the router sometimes loses the 5GHz network and I have to restart it. We were away until yesterday and the WUSB600 has been dropping the wireless connection a few times.

AirPort Utility in Windows - cannot set 5GHz channel manually

I am trying to manually set my 5GHz channel to something other than automatic. I change it to
and click the update button. The router restarts and my changes do not stick. It now shows
The 2.4GHz channel can be modified but not the 5GHz. Anyone have any ideas?
Thanks.

So are you saying that it does not work with v6 on an Apple product either?
That is the info I have at this point in time. I have totally avoided AC models.. I think they are poor cf the same chipset models available from Asus or Netgear that have real GUI setups with real functionality.
Is there functionality that is available in the Mac version but not in the Windows version?
The v5 utility in Mac and PC was the same functionality..
The v6 utility in Mac and never released for PC has far less functionality. Which is designed I guess to correspond to the new model Apple routers which also have less functionality. For instance there is no longer a log function you can use. Apple do not believe in functionality.. it is supposed to be as near to self setting as possible.. the ideal would be purely automatic and no airport utility. Apple are slowly working towards their nirvana.
Why has Apple neglected to update the Windows version? Looks like the Windows version 5.6.1 (Post Date: Jun 11, 2012) is a year older than the Mac version (Post Date: Jul 11, 2013).
Apple do not reveal info like this.. but my guess is they produced an iOS version so they figured if you don't have a Mac then surely you own an iphone or ipad.. if not you should buy one.

Airport Extreme 5GHz Channel not available

Hi All
My Airport Extreme 5th Gen is now up and running.
The issue I have is that unless I give the 5GHz channel it's own name, my MacBook Pro will not pick it up - instead opting for the 2.4GHz channel. I know that distance and obstacles are a factor but in a test situation the MacBook is only a metre away from the Airport. If I give the 5GHz channel it's own name then I can select the 5GHz network and confirm the connection rate - this also works with Windows 7 machine in the same position with the signal strength being 'excellent'. So why when I have the same name for both channels will my machines only pick up the 2.4GHz signal?
Using two names would be okay exept that when I do this the 2.4GHz network slows completely and is unusable.
Last week I had a pretty good setup with an old Airport Extreme and now with the new 5th Gen unit I can either connect two machines at 5GHz or four machines at 2.4GHz - not a mixture of both. So basically I'm no better off than with my eight year old Airport Extreme.
I'm beginning to think that there is a defect with the new Airport Extreme unit - is there any simple checks I can do on the unit to confirm that it is operating correctly?
I'd really appreciate any help with this.
Phil

Update: Solved. I reset the Airport Extreme a number of times in succession and finally it just worked - not sure what the problem was.
