Linksys Wireless Router :: E3000 5Ghz Auto(DFS) Versus Selecting Channel
Nov 15, 2012
I have an E3000 Dual Band. On my 5Ghz channel, I can select Auto(DFS) or I can manually select a channel.First of all, what does the DFS stand for? My 2.4 GhZ channel only has Auto, not Auto(DFS).
Second, when I select Auto(DFS), my wireless speed defaults to 144Mbps, and is only a single channel (I can see it in the in SSIDer utility). When I manually select a channel, no matter what channel it is, I get 300mbps and I can see that the signal is two channels (for instance, 36+40). Why Auto(DFS) doesn't automatically select the best channel and fastest speed?

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?

My desktop pc has an Asus PCE-AC 66 PCI card (supports up to 1300 mbps wifi) and is only 5m or so away from the the EA6500 router without any obstructions - yet i cannot connect at 1300 mbps AC wifi. On the EA6500 router, i have selected 'mixed' as network mode under 5ghz (since i have some other devices which connect on wifi N on 5ghz) but if i select channel width as 80mhz, i have issues connecting to the 5ghz network on the desktop pc. The desktop briefly connects and under status it says lan speed as 1.3gbps but then it disconnects and i can't connect again. If i select channel width as 'auto' then no problems, the desktop can connect but lan speeds are only 400-600 mbps. why i cannot connect at 1300 mbps?

Wednesday, November 23, 2011I have an Airport Extreme dual-band 2.4Ghz and 5Ghz. Each network is has a different name and different password so I know exactly which one I am connected to.On a MacBook Pro, it sees both networks. On a Dell E5520 it will see both networks. On an iPhone 4 it will see both networks. I can connect any of these devices to either network.Just got the Linksys E3000 dual-band 2.4Ghz and 5Ghz. Each network is has a different name and different password so I know exactly which one I am connected to.On a MacBook Pro, it sees both networks. On a Dell it will only see the 2.4Ghz network. On an iPhone 4 it will only see the 2.4Ghz network.The Airport Extreme is powered off when using the E3000 so I know there is no interference from this router.E3000 Firmware Version 1.0.04. It's the latest.5Ghz Wireless Settings
Network Mode: Mixed
Channel Width: Auto (20Mhz or 40Mhz)
Channel: Auto (DFS)
2.4Ghz Wireless Settings
Network Mode: Mixed
Channel Width: Auto (20Mhz or 40Mhz)
Channel: Auto (DFS)Did not mess with any other settings. I have rebooted the computer, cycled the router and modem 3-4 times.Nothing works.My question is since both laptops and phone can see the 5Ghz network when running the Airport Extreme, why doesn't the 5Ghz network show up on the Dell and iPhone when running the E3000.

I've not been able to connect to my to Linksys E3000 when set to 5GHz "N" only Network mode. Connections to the 5GHz can only be done in mixed mode. I do not need to have A-Mode enabled, so I do not wish to use mixed.

I've had the wireless G adapter for a year now, and connections work with both 2.4GHz and 5GHz G connections. I just bought a wireless N adapter (2.4GHz and 5GHz capable), and cannot get an N connection.. On 2.4GHz it connects to G only. And on 5GHz, I don't even see the whole band to connect to it.
I've tried disabling the 5GHz band on the E3000, then even setting the 2.4GHz band to no security. I still get a G only connection.My laptop can connect to 2.4GHz and get 144Mbps N speeds.Router is at latest firmware.I've researched this online, but can't find anything concrete.

I have read various forum postings saying to get the best performance from a wifi router you have to use channel 149 or greater and that 36-48 have a weaker signal strength and thus less range/speed.I live in New Zealand and when I select the wireless channel drop list for the 5GHz band it only lists 5 options - Auto (dfs), 36, 40, 44 and 48. I have read forum posts of people stating you should switch to 149 or greater and I have seen screenshots showing the drop list with 149 selected. But I don't have that option.If I check the Status > Wireless page it shows that channel 36 is being used (for Auto).Am I doing something wrong? Do E3000's in this part of the world not support 149 etc?I spoke in a live chat to a support rep who told me that all E3000's are the same everywhere in the world and there was little to no difference in firmware between them. I was also told that channels 36-48 are high gain channels and so there is no need for the other channels, which contradicts other articles I have read which state 36-48 are weaker channels.

How do I know if I'm using 2.4 or 5ghz? I would like the laptop and ps3/net flix to use the 5ghz and everything else to use 2.4ghz. I used the e3000 CD fro the setup. When I was at the last part of the setup, when it gives you a ssid name and password. I deleted it and typed in a name that I could remember. I clicked the button for the next step and everything was complete. I also received another name for guest to use the computer. The e3000 setup just game me some wild name like running water.
I would like to know since I have two different names, which on e is using 5ghz and which one is using 2.4thz? Can you tell me if the e3000 automatically have the first name use 5ghz and the guest just 2.4ghz on the second name?

My E3000 has about 60% packet loss if the channel selected is anything other than 1. I can't enable 5GHz or even 40mhz 2.4GHz channels without dropping 60% packets.

I have a Dell E6420 running WIN7 32bit. It is running the Dell broadband utility. I am trying to find a way to keep the users from selecting auto-connect in settings>config. I am looking for a registry key or something that can be done from the admin side to stop this.

I have the new XBOX 360 black N wireless adapter and the Linksys E3000 dual band router as I want to upgrade the network range and speed to N. I set up a unique SSID and passphrase (WPA2) for both 2.4GHz and 5GHz bands. My XBOX could connect to the 2.4GHz band network and could connect to XBOX Live. But when I configured all the settings and tried to connect to the 5GHz band network, but no luck. My XBOX just said it failed to connect. I was sure that I did type in the SSID and passphrase correctly. I still cannot figure out what went wrong. I even suspected either the wireless adapter or the router malfunctioned.

I'm looking at a dual-channel wireless-N router that transmitts at 2.4Ghz and 5Ghz, but none of our newer laptops even recognize the 5Ghz channel. Is there a configuration setting to change what frequency laptops can recognize? Looking to put 2 newer modle Toshiba loptops on the 5Ghz channel and leave two other...older systems on the 2.4Ghz channel.

A few months ago we upgraded our warehouse from 1242 APs to 3502E APs. We changed 16 units, all in the same building. When we came in the next day we found out that they were all on channel 1 at their lowest power level. The WLC was set for auto negotiate for power and channel but for some reason it did not work. We had successfully changed they rest of the factory with the auto feature enabled but for some reason, the warehouse did not work properly. All APs have the same IOS and are they same model. We have WiSMs mounted in a 6509 chassis as our WLC.

We have a switch that, when configuring auto qos on and edge port facing video equipment, the upstream port channel drops. I was wondering if no auto qos would have to be configured on the member ports of the port channel prior to enabling auto qos on any other ports.

BEFSR81 v3.0.I selecting Enabled UPnP and now I cannot access the router. When I enter the default admin for the password in the Authentication Required screen. I get the following screen: 401 Authorization RequiredThis server could not verify that you are authorized to access. Either you supplied the wrong credentials(e.g., bad password), or your browser doesn't understand how to supply the credentials required.I didn't enter anything new into the username or password fields.

I have a 4510R-E chassis with SUP7-E running IOS XE version 3.01.01.SG. I am unable to create a port-channel and apply auto-qos for VOIP.If I configure auto-qos on the physical interfaces, I get this message when I try adding them to the port channel:
"The attached policymap is not suitable for member either due to non-queuing actions or due to type of classmap filters."
Auto-qos is not an available command in the port-channel interface configuration, but if I try adding the service policies that were created by auto-qos to the port channel manually, it lets me apply the input policy but on the output policy I get this message:
"A service-policy with queuing actions can be attached in output direction only on physical ports."
With the input policy applied to the port-channel interface, I tried addign the output policy to the physical ports and I got this message:
"A service-policy with non-queuing actions should be attached to the port-channel associated with this physical port."
Is there a way to get the auot-qos policies applied to the port-channel properly?

I just got a new E2500 and out of the box the system uses the same SSID for 2.4 GHz and 5 GHz. Obviously you CAN configure them to use different SSID's, though. Should I make them different or keep them the same? I don't really want to mess around with having 2 different SSID's if I don't get a real benefit.Will most devices that support both (like a new laptop) find and use the 5 automatically?

My son tried to "speed up" our connection by unplugging modem&router. now can't get both talking to each other. Tried numerous steps! Bought Router 8/11/11, so NO Support from Cisco(only 90 days-POOR!). Website useless. Modem works fine with PC wired in.

I have e4200 router set up with different SSIDs for 2.4ghz and 5ghz. My laptop (Lenovo x220 with Intel 6205 wireless adapter) can't see the 5ghz network. I've tried changing the channel for the 5ghz network and it didn't fix the problem.

I am using the E2500 with the Wireless N-pci adapter with dual band, both with the latest drivers / firmware, and I am getting extremely low signal quality and connection speed when connecting to the 5 Ghz network.My computer is no more than 15 feet away from the router, and on the same level. I also verified the connection with the 2.4 Ghz band, and it reads as excellent, and with 54 mps. Using 5 Ghz I get one bar of signal quality (very poor) and no more than 13 mps connection speed.

I've found a few people with this problem on the internet. I'm using my phat 360 with the black N adapter. e2500 is updated to the latest firmware. But my 360 cannot connect to the 5ghz N, only 2.4ghz g. The wierd thing is that the 5ghz signal gives a better signal than the 2.4ghz.
I just found a thread on google talking about the e4200 and someone mentioned counterfit adapters and problems with them. I did buy this on ebay for a cheap price, so it looks like it was too good to be true. this is a counterfit? It does have a real hologram on it.

If this is real, what else could be the problem. Has the firmware not been updated to support the 360?

EA2700v1 WPS-PIN using 5GHz does not work. This router includes WPS header in its 5GHz beacon and probe response but the router removes the WPS header from them once WPS-PIN starts. There is no problem with WPS-PIN using 2.4GHz.

The EA4500 web-settings application asks for a username and password. The username is "admin" and the password is my long (60 character) wpa key. I see where I can change the password but it says I'll lose all wireless connections. This doesn't make sense to me. I would think the router administration username and password are completely separate from the ssid and wpa key. This was the case with my earlier LinkSys router. I'd like a router administration username to be something other than the generic "admin" and a password that is easier than my long wpa key. I want a separate ssid and wpa key (what I currently have).

I got my WRT54GL v1.1 yesterday and connected it to my pc [wired] and netbook [wireless]. I thought all was well until I noticed that my Magic Jack VoIP telephone began dropping calls after about 1 minute. My first course of action was to disable SPI firewall in router and reboot. That had no affect on the situation, then I noticed that my send light on my cale modem [ no manufacturer listed on unit] was not blinking as it has done before the router installation. I reverted to my cable modem to pc only set up and my Magic Jack worked just fine. I need to use the router for wireless, so I need to find a solution to this problem. I took a look at my firmware version and saw that it was not current, but I wanted to bring my problem here for a possible solution be for I flashed new firmware.

I have found that if I do not enable the broadcast SSID option on my 5GHz N network that my devices will forget the network and not reconnect on their own. Yet, I have the 2.4GHz G/N network set up to not broadcast my SSID and I have no problems. Why can't I disable my SSID broadcast on the 5GHz N network without these problems?

I ended up with an RMA for a new E4200 ver. 1 and the problem I have still persists. My 2 GHZ WAP gets 65Mbp/s to its connected devices. However, the 5.4 GHZ WAP gets 48 to 54 Mbp/s only.My laptops have Windows 7 and Ubuntu. The WiFi cards are Intel Centrino Advanced-N 6200 and 6230. Both fluctuate at 48 - 54Mb/s on the the 5.4GHZ channel.
If I put it on Wireless-N only, the laptops cannot connect. I have tried AUTO detection for mhz and channels. I have tried 40mhz with channels 149 and 161 with no difference.Currently, I am operating both WAPs on different SSIDs to make sure my results are separate.Security for both WAPs is WPA2-Personal with a 10 digit sequence.

I purchased the linksys 3200 dual band router recently. I am a huge cisco and linksys supporter so for me this is disappointing. Aside from being slower at times than my previous router I am having issues with the 5Ghz wireless. My issue I am facing is it seems multiple times throughout the day the router somehow drops its 5ghz wireless ssid or its gone..not sure. The only way I can get it back up and running is to reconnect with the Cisco Connect software and re-establish the settings and then reconnect any wireless devices. This seems to happen sporadically and is insanely annoying considering this router should be a big upgrade.
It seems to me the 2.4Ghz band seems to be more stable. I am on the latest firmware for the device and I am using a 5ghz compatible wireless device to connect to it.

Router: E4200
Router Firmware: 1.0.03 (Latest FW)
Why I cannot go to the 5Ghz band to utilize the superior speeds to transfer files over wireless connection between my computers? I am sure that I am still on the default 2.4 Ghz because
1) The file transfer speeds are pathetic
2) In Wireless Security, if I set the Wireless Mode to disabled for the 2.4Ghz band, Windows shows me "Unsecured Network" even with 2.4Ghz disabled.

I have the E4200. I have two networks, a 2.4 for internet, and a 5gHz for media. I want to have a wired connection to the 5gHz network as some of the media is on my PC. However, it seems I can only have a wired connection to the 2.4gHz network. Is there any way to do this?
