Lenovo Yoga 2 Pro connecting to 5ghz dual band wifi?

I just found something strange. Under Windows, my lenovo yoga 2 pro does not see my 5ghz wifi connection (from my dual band router). But I just booted under Linux Mint, and was able to connect to the 5ghz connection without issues. Any idea why this would be?

Dual Band: 2.4GHz and 5GHz at the same time:
Your MBP can connect to both.
If the Bands each have a different Name, you can choose by hand, if not it connects to the strongest signal.
Click the wireless icon and you see the name of the network you are connected to, If you see the other band name you can choose that.
Click the wireless icon in the menubar while hoding the Alt(option) key: it gives the specififcs of the band you are connected to.

What dual band wifi adapter for HP ENVY x360 15-u205na

What dual band wifi adapter is compabible with the HP ENVY x360 15-u205na please. It is somewhat disappointing that a current laptop is still only single band 2.4Ghz, if I had known before purchasing the HP it would certainly have changed my purchase decision.

Hi,
This is an Intel based laptop so you can use Intel 6235 or 7260AC I guess. Go for the 6235. It's a decent wireless card..

Dual-band wifi dongle differences

From the following pages
https://www.productsandservices.bt.com/consumerProducts/displayTopic.do?topicId=36119#tab3
https://www.productsandservices.bt.com/consumerProducts/displayTopic.do?topicId=36895#tab3
I can see the homehub 4 and 5 with optional dual-band wifi dongles.
What's the difference between the £9 dongle shown under the homehub 4 page and the £19 dongle shown under the homehub 5 page?
Also, if one has Bt Infinity but a homehub 4 is the £9 dongle the one to go for?
Thanks.
Solved!
Go to Solution.

The £9 dondle works on the 2.4Ghz and 5Ghz on b/g/n frequencies where as the £19 works on the 2.4Ghz b/g/n and 5GHz on the new AC frequencies which can give faster speeds.
If you have the HH4, which does not transmit AC, go for the £9 one.

Can the imac core duo support dual band wifi?

I have a core duo 2GHz iMac intel. Can the imac core duo support dual band wifi?

Do you mean will your iMac work with a router that supports dual band? If this is correct, the answer is yes. If that isn't what you intended please look at the system specification for your machine. You can find that by clicking Support - Tech Specs

Dual band wifi support

Which Mac minis support dual band wifi?

Further investigation:
802.11n spec does not require the 50Ghz radio and some of the early "n" implementations were not dual band. However, I looked in my "about this Mac" system report (late '09 mini) and it showed a number of channels supported above the first 11 which are in the 20 Ghz range. So I am sure it supports the 50Gz radio and is dual band. Maybe all Mac "n" implementations are dual band!

Printers connected to a dual band network

How can I have a laser printer seen by the two networks setup by a dual band extreme?

Thanks for the reply and potential solution Tesserax.
Here is the detailed (and long) version of my problem. I bought a Lexmark S608 printer thinking that since it supports wireless n, that all would be good and I could print and scan wirelessly. Unfortunately, the S60x only supports wireless n in the 2.4GHz band.
So if I downgrade my wireless n to 2.4GHz, the MacBook, Mac Mini and S608 are on the same network and can print and scan wirelessly.
The problem is that even watching YouTube video wirelessly is not possible on the n 2.4GHz band; it stops every few seconds to buffer. I guess I have a lot of interference where I am in the 2.4GHz band (and I don't have 2.4GHz phones). I have tried different channels on the 2.4GHz band but with no success; since I switched to the 5GHz band over a year ago, all has been very good. I tested copying files locally from/to the MacBook and the Mac Mini and wireless n 2.4GHz takes more than five time longer on average than wireless n 5GHz.
If I share the S608 on the TC USB port I will be able to print wirelessly from both the MacBook and Mac Mini, but won't be able to scan from either.
For now, I've attached the S608 to the Mac Mini via USB. I shared the printer via the sharing control panel and that works fine. But I shared the scanner via the sharing control panel and that does not seem to work; I cannot access the scanning function using Preview from the MacBook for example (whereas this was possible when the S608 was connected wirelessly on the n 2.4GHz band).
I looked at creating a WDS network but I have not tried yet because everything I've read says that it will halve your speed at best (and including g (for the printer/scanner) and n seemed to be problematic for most).
So I don't think it is possible, but I was therefore wondering if the dual band feature of the latest TC or AEBS would allow clients to see each other, bridging the 2.4GHz and 5.0GHz network together.
All that to say that the S608 is still a fine printer for my needs, but it would have been practical to be able to scan wirelessly from either the MacBook or Mac Mini. So buyer beware!

Wifi connectivity - Yosemite and dual band routers (i.e. BT Home Hub)

This is working for me so far after all previous tips on other Discussions proved only to be temporary. This is the only one that enabled my MBP to accept password for the SSID.
From BT Home Hub - 2011!!
The BT Home Hub 4 and Hub 5 are dual band with two wireless frequencies for devices to connect to: 2.4GHz and 5GHz. On both Hubs, the default setting has the same network name (or SSID) for both the 2.4GHz and 5GHz bands. Connecting a typical 5GHz-capable device to this single SSID will automatically connect the device to both the 2.4 and 5Ghz frequency at the same time.
However, not all dual band devices behave the same way and some device software does not cope well with a single SSID for both frequencies.
As a result:
the device may not connect wirelessly to the Hub
it may not connect to 5GHz frequency even in the same room
the wireless connection might be intermittent
the wireless connection might be very slow
Devices where there are known to be problems include:
Some Apple devices including iPhone 5 and Apple TV
some Android smartphones
Xbox
For some devices you can solve this problem by having different network names (SSIDs) for the 2.4GHz and the 5GHz bands. To set this up, follow these steps:
Open your web browser on a device connected to the Hub and go to bthomehub.home. This will open the Hub Manager
Click on Advanced Settings and enter your Hub admin password when prompted. Unless you've changed it, you'll find the default Hub password on the Hub settings card
Click on Continue to Advanced Settings
Click on Wireless
Click on 5GHz
Change 'Sync with 2.4 Ghz' to No
Change the 'Wireless SSID' to a new name (we recommend just adding '5GHz' to the end of the existing SSID name so you'll know which one is which)
Click Apply to save the changes
After a few minutes you should see two BT Home Hub SSIDs in the list of networks on your device. All of your devices will still automatically connect to the original SSID name, which will be the 2.4GHz.
If you have existing dual band devices you want to connect to 5GHz only, you'll need to connect them to the 5GHz SSID that you've renamed. AND RESTART the hub - PJ
Note- Even though wireless speeds at 5GHz can be significantly faster than 2.4GHz, the range of a 5GHz connection is not as good. As a result, you may need your device closer to your Hub (than you'd need to when using the 2.4GHz SSID) to get the best performance possible."

Sadly it didn't last...
I just posted this on BT Home Hub users forum. and the big Yosemite/wifi Discussion
"Sorry to awaken this topic from the dead....
I am using HH5a, opted in to FON, and Os10.10 MacBookPro
I have no problem whatsoever connecting and staying connected to 2.4ghz
I struggle since OS10.10 to either connect or stay connected to 5ghz
A persistent issue with trying to connect to 5ghz is the response "invalid password" Only occasionally in the past 3 months has this not been a problem
the app WifiExplorer shows today that the only other networks on the same channels as my networks are the FON wifiX - both of which I presume are using my router/wifi as when I manually change channels these move with me.
Signal strength on 2.4 ghz is between 77 - 85, 5ghz 80+/- 1
Noise and signal noise ratio a lot higher on 2.4 than 5
(There is lots more info on wifi explorer but I dont know its relevance/meaning)
I have tried using manual channel selection and Smart Wireless and can't see much difference in 5ghz connection
Given a choice I would prefer to stay in FON but if there is overwhleming evidence that these hot spot networks are affecting mine, I would consider opting out. Views/ guidance please. Thanks. And a Happy New Year too."
IS ANYBODY ELSE using BT Home Hub5a having this same issue? I BELIEVE it has largely if only been since upgrading to 10.10.1 but can't swear to it.
IS IT SIGNIFICANT THAT SOMETIMES THE PASSWORD TO 5GHZ network is accepted and other times not?

Time Machine: External Hard Drive connected to a dual-band network

I currently have a dual-band network setup using a 1TB Time Capsule (wireless-n only) and an AEBS (wireless b/g) in bridge mode.
My unibody MBP and ATV utilize the Time Capsule, while an older Macbook and MacMini utilize the AEBS. I have Time Machine configured on the MBP to use the Time Capsule for backup.
I have connected an external 500GB hard drive to the AEBS for the purpose of using Time Machine for the Macbook and MacMini. The Airport Utility shows the external drive connected to the AEBS, but when I try to configure Time Machine for the Macbook and MacMini I am only allowed to select the Time Capsule as the destination. Sorry for the long post. Any help would be greatly appreciated

Assuming you have the square Extreme (not the UFO-style), you can use an external USB HDD with it.
Time Machine backups to AirDisks (e.g. USB HDD attached to Extreme) is unsupported, but has been successful by some. As well, once you decide to move any old TM backups (HDD connected directly to the Mac) to an AirDisk, you cannot continue backing up to your previous TM backup. The format it saves to vs. a local HDD is different. The folder structure you see becomes a sparsebundle/disk image via the AirDisk.

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.

Unable to connect to 5ghz network band with security/password

Hi, I've recently set up a 5ghz network band on my router. The problem is I can't connect to it while it has password enabled. However, I am able to connect while it has no security/password. I would like to connect to the router using some kind of security or password
I am using a Netgear Router WNDR3400v2.

You need to contact Netgear for support, it's their router they would probably know how to support it best.

Connecting ap extreme (dual-band) to ap express b/g via wds

main question: can i have two b/g ap expresses extend the b/g signal from a main dual band station?
either this is way complicated or i'm really slow (i know). i have a new-ish ap extreme dual band (v. 7.5.2) and two older ap expresses (v. 6.3). i thought i was extending the extreme's b/g signal by choosing the "join a wireless network" option, and just learned that option does not extend the b/g signal. maybe i am slow...
i learned that the ap extreme dual band's checkbox "allow the network to be extended" is only for other N wireless airports (counter-intuitive). i learned that trying to make my remote (but not relay!) ap expresses participate in a wds network, first, causes them to need to be reset. every time. i learned that i need to make the wds setting on the main station FIRST, and option-click on the wireless mode menu (counter-intuitive? sheesh!) i've read several posts about people having problems (one person said apple doesn't really want us to use wds, so that's why it's hidden). i found this page and did all the steps on the main station:
https://discussions.apple.com/thread/2355832?threadID=2355832&tstart=0
and the result was an amber light w/ a wds error (i saw the amber light in the airport utility window, i didn't check to see if the unit was blinking).
neither the above link, nor the pdf mentioned (http://manuals.info.apple.com/en_US/Designing_AirPort_Networks_10.5-Windows.pdf) pages 42-46 mention a wds error or what to do.
w/ the wds error, i still had internet, but could not access the other two b/g ap expresses to make them wds remotes.
2nd-ary question: why is this so hard? why the secret option-click menu? why doesn't the apple help utility spell this out (it only mentions N airport, and says for other devices, to "check the Apple Support Website.")? there are so many posts on this, some are poorly worded (maybe mine too!), some are slightly different scenarios...
any help is greatly appreciated.
marc

Marc,
I would suggest that you decide whether to move back 5-6 years and use WDS....with a tremendous loss of performance on your dual band Extreme....(It becomes a "g" wireless router using WDS and the bandwidth of your entire network will drop by half for each AirPort Express you have on the network).
So, instead of "n" wireless at 130 Mbps, your WDS setup will yield 13 Mbps at best. WDS is very difficult for most users to setup because it is very easy to make a mistake and hard to find your way out when you do.
The "Extend a wireless network" setup will maintain "n" speeds on the entire network with a very small bandwith loss. But, you have to use all "n" devices for this to work, and you can only have "main" and "remotes". There are no "relays" in this setup. It is a much easier setup to configure than WDS.
The Apple document below provides all the details. I could not tell from your post whether you had looked at this.

Supported Dual Band Wifi Card for s230u Twist?

I just bought the s230u Twist and realized that the Intel 2230 wifi card is *not* dual band (2.4 GHz only). I also realize that the BIOS has a whitelist for mini-pci cards and need to know if there are any dual band cards that are supported. Thanks.

Hey there guys,
Jccheng, the ThinkPad a/b/g/n Wireless & Bluetooth 4.0 (2x2 ABGN & BT 4.0) is a dual band adapter that is compatible and comes as upgrade with the ThinkPad Twist s230u. The 802.11a only runs on a 5Ghz Frequency, and the 802.11n can run on either. I have listed all the adapter options with part numbers below:
04W3763 Cybertan BCM43228+BCM20702 abgn WLAN & BT 4.0 Combo (ThinkPad a/b/g/n)
04W3764 Liteon BCM43228+BCM20702 abgn WLAN & BT 4.0 Combo (ThinkPad a/b/g/n)
04W3765 Intel 2x2 11bgn + BT4.0 Combo Jackson Peak1 (Centrino 2230)
As an option, you can call the Lenovo Contact Center, 1-800-426-7378, for a Parts Only order. Hope this helps!
