Dual band card - U400

I have upgraded to a dual band router. I was wondering if it is possible to replace the card in the U400 with a dual band card. I know it will fit based on the size/type of card but I didn't know if it had the correct antenna. I don't want to purchase and install the card to find out it isn't able to use both bands. Any advice would appreciated. Thanks!

hi perrinjcat,
Welcome to Lenovo Community Forums!
Lenovo System has a limited support for Wifi adapters it has a Whitelist of parts compatible and those parts are marked with an FRU number,
Here are the parts stated to be compatible on your system
Highlighted are the FRU Number,
NOTE: The WIFI card should be marked with the listed FRU.
Same part model with no FRU will not work.
Best Regards
Solid Cruver

Need Recommendation for Windows USB 802.11N Dual Band Card for AEBS

I am building a very large WiFi network to support 100 users. The plan is to use only Dual Band Airport Extreme Base Stations.
Can anyone recommend a compatible USB adapter that will work on Windows (XP, Vista, & Windows 7)?
Looking for something that has 802.11n + 2.4GHz and 5GHz bands.
Any help is appreciated. (Google has been help to tell me what WON'T work... leaving me concerned that my network is going to have issues when it comes to PC users).

The one PC that is running Windows 7 which is the only PC running Windows 7, the rest are XP or Vista has a Atheros AR5007 wireless card keeps dropping connection to the airport. The computer is a HP Pavilion 1448dx. Does anyone have any suggestions for me to fix the signal drop to that computer, all of the other computers are fine.
Yes, please check with either HP or Atheros to see if there is an updated driver for the wireless card.
Another quick question: I was wondering if I could hook up my previous router (Belkin Wireless G Plus MIMO Router) to my Airport Extreme and have the PC's run off the belkin and my mac just run off the Airport Extreme and solve the issue with the one PC dropping connection.
Yes, it may be possible. The Belkin would have to be connected to the new 802.11n AirPort Extreme Base Station (AEBSn) via an Ethernet patch cable and reconfigured as a bridge. In addition, the Belkin's wireless radio channel should be changed to one at least 3-5 channels away from the AEBSn's channel.

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!
Ophion, are you looking for the Intel Card for a specific feature?

Dual band wlan adapter replacement

Hi, I have an HP pavilion DM1 4310sw and I would like to replace the WLAN card. Inside there is a Ralink 3290 b/g/n/2,4Ghz only. I want to have dual band wlan card with bluetooth. Which wlan card will work with my laptop?
Thank you for your help

Hi Rapi,
Welcome to the HPCommunity, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I see that you are looking for dual band card for your Pavilion. I took at a look at the specifications for your model and there isn't a particular card that I can recommend. Not of the wireless cards recommended in the Maintenance and Service guide are dual band. There is one that is but only if your model has an Intel processor but yours has a AMD dual-core according to the specifications.

Re: Dual Band PCI Card for Satellite C660

Hello, please can someone suggest any dual band PCI card for Satellite C660
thanks

>Dose it mean this forum if not supported by Toshiba?
Buddy, its a user to user community
Regarding the miniPCI WLan card:
Such part upgrade is not officially supported and therefore details about compatible cards are not available.
But from my knowledge many different notebook series have been equipped with different WLan card from Realtek, Intel and Atheros.
Probably such cards would be compatible even if they are not listed officially as supported part.

H520 wireless card (realtek 8188e)-does it support dual band router

Solved!
Go to Solution.

hi Dia,
As per this pdf data sheet, the Realtek RTL8188EE is a single band (2.4Ghz) Wi-Fi card. If your router is a dual-band, you need to configure it to broadcast 2.4Ghz frequency so that the Ideacentre H520 can connect. Otherwise, it will not be able to connect to the 5Ghz band.

Airport exytreme dual band with a wired ethernet card

Hi!
i just want to know if it's possible connect my airport extreme dual band, without a wireless card, just the regular pc etherneet cards?

Yes, you can connect a wired device to one of the LAN ports on the DB AirPort Extreme Base Station (AEBS), by Ethernet, for connectivity.

Where do I order a dual band NGF (M.2) card for my T440s?

I've searched high and low. I'm an engineer and am capable of installing this module myself (I've tried others which are blacklisted in the BIOS so I cannot use them).
Lenovo,
Can you provide me a link to order a Dual Band Intel NGF (M.2) card for my T440s?
Thanks!
Terry

And just FYI, this thread:
http://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/Yoga-2-Pro-WiFi-Replacement-Cards/td-p/13...
States that the M-Factors card works in some Lenovos. It DOES NOT work in the T440s (BIOS whitelist error).
Last Lenovo I will ever own, and I am the one making the hardware recommendations for our company.
Lenovo have made this whitelist crap for way too long now.

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?cc=us&lc=en&product=6761918
For the wireless card, very hard to tell since HP only give you few choices on page #7.

How can I get Wireless N 5MHZ Capabilities Dual Band up to 300MHZ on my DV7 Laptop?

How can I get Wireless N 5MHZ Capabilities Dual Band up to 300MHZ on my DV7 Laptop?
Question for 4/18 experts ...
Or specifically, how can I replace my wireless card on a DV7-6B32US and upgrade to Intel Centrino 6230?
I have a relatively new DV7-6B32US puchased on 11/2011. Still under warranty. purchased 2 of the laptops. (also own 3 hp desktops and 1 HP All in One)
Existing card is wireless N but does not support 5GHZ or dual band. It is Broadcom 4313 wifi card and I am just realizing that the Broadcom card does not do the dual band 5GHZ wireless N. I have Linksys e4200 router which supports 5GHZ and dual band speeds up to 300 Mbps.
I called tech support and with their help identified Intel Centrino 6230 as the correct upgrade, and with their help ordered 631956-001. In the Maintenance Manual for DV7 laptop, this part number was listed for Intel Centrino 6230. Turns out HP sends an Intel Wireless N 1030 card, which is no better than my existing card. I called HP and they acknowledged that some manuals use part number 631956-001 for Centrino 6230 and some use 631956-001 for INtel 1030. So HP support said they would give refund but case manager was of no help in solving the upgrade problem. Said it was unavailable but here is your money back.
So after more searching, I see others have used part number 636672-001 to order Intel Centrino 6230, specifically for HP ProBook 4530s, 4230s, 4730s. And if I use part number 636672-001 and go thru parts store at HP, I can purchase it.
But will it work??
First, will the Intel Centrino 6230 with part number 636672-001 from HP parts, work in my HP DV7-6B32US, even though the part number is NOT listed in the Maintenance and Service Guide for my specific laptop. I see postings about whitelists and changing bios, etc, and am hoping someone can provide some guidance. I have been thru 2 tech support calls and one case manager and have gotten 3 different feedback from HP, from yes it will work and ordering the part, to buy it on amazon, to it will not work and here is your money back.
Second, I see some postings about Centrino 6230 and multiple antenna's. When I replaced the Broadcom 4313 with the Intel 1030 card, I simply unattached 2 wires and reattached the wires. And it worked. I am wondering if the reason HP doesn't list the 6230 card for DV7 is that DV7 does not have the antennas required to support 6230. Does the Centrino 6230 require 3 antennas?
Thanks for any suggestions. The existing cards do work but I paid extra for the Linksys e4200 Router and just assumed a winter 2011 $700 laptop from HP would use the latest wireless n technology, otherwise I would just keep existing cards.

I have went thru the exact same problems trying to upgrade the wireless card in my DV7. It is very frustrating that the wireless card can't be upgrade to one that supports 5Ghz. Here is my post from the network forum. http://h30434.www3.hp.com/t5/Wireless-Internet-Home/Unsupported-Wireless-LAN-6230/td-p/1419595 Doesn't sound like it is possible to upgrade to the Centrino 6230 without it being added the the "white list". Sound like HP doesn't update the list after shipping the notebook. I feel your pain. HP needs to help out the consumer in upgrading the wireless cards. I see we are not the only ones that have had this problem.

Dual Band (5ghz and 2.4 ghz) Wireless Network Config and Dropped Connection

Hi, I have an Airport Extreme (802.11N) and a Motorola WR850G (802.11A/B/G) that I'm trying to connect in a dual band setup - but something in my setup is causing the Airport to drop it's connection (before the connection is dropped - everything works great). After I lose connectivity, both routers show up in my list of wireless networks, the light stays green, but I don't have local or internet access. When I try to reconnect, the log on times out. Also, the Airport isn't displayed in the Airport Utility (light is green on the airport itself though). Unplugging and resetting the Airport Allows all computers on the network to connect locally and to the internet for a few hours until the connection drops again. While it is up and running, I have no problems streaming movies off the connected Airdisk, navigating the internet, and connecting both N and G devices to the network.
I'd love to hear from you if you've gotten a similar setup to work, and if possible, have you provide the settings you used to make this work. I've looked around quite a bit and haven't seen a detailed description of the process (even from the Apple documentation). Also, advice from anyone would be greatly appreciated since my wireless networking knowledge is pretty basic.
My configuration:
Time Warner cable modem connected to the Airport's WAN port. WR850G connected by LAN port to Airport's LAN port. Bridge Mode check box selected on WR850G. Airport setup for 802.11n (5Ghz). Unique SSIDs to determine which network is 'N'. Same password for both networks. My Firmware and utilities are up to date.
Computers/Devices on Network:
Two Macs with Airport Extreme N cards. A Vista PC with a D-link N card (only compatible with 2.4 Ghz so it connects to the G network). A Vista PC with a GB ethernet card connected to the Airport Extreme. Various other G devices like iPod touches and an old iBook. Airdisk connected to the Airport Extreme.
Thanks,

I removed the second router (Moto wr850g) and everything seems to be working smoothly. It must be some settings on that one that are causing the problem, but I haven't been able to get it configured correctly. I noticed there were some IP conflicts with my wireless wanting to use the old Moto router IP and trying to assign my Mac an IP from that router. Does anyone know specifically what needs to be disabled on a router in bridge mode? Since I have a third party router there aren't any handy wizards that can configure it for me.
Thanks again

Dual Band Network: Time Capsule (N only) and Linksys (B/G) Works *Long*

Ok, so this was more tedious than I thought it would be, but things actually seem to be working at this point.
Goal: Create a Dual Band network with Time Capsule (N only) and a Linksys WRTSL54GS (B/G)
Time Capsule: 1000BaseT wired, and 802.11N 5Ghz only wireless
Linksys: 100BaseT wired, and 802.11G 2.4Ghz wireless
Airport Utility 5.3.1
Time Capsule v. 7.3
I set Time Capsule up first, following the step by step directions for "Create a wireless network"
802.11N only, 5Ghz
WPA2 Personal
DHCP 192.168.1.1 (kinda important)
This worked fine-tested on a C2D iMac, both thru ethernet and wirelessly thru N. Time Machine backed up fine.
Now the tricky part, configuring the Linksys.( I just want to mention I had to reset this thing completely about 10 times to get it to work, using a miniscrewdriver)
Starting with a freshly reset Linksys, I connected from my MacBook ethernet port to one of the Linksys ethernet ports (Not the WAN)
I disabled Airport
I logged in to 192.168.1.1 using blank for login, admin for password (default for Linksys)
I did the following:
1) Confirmed Internet Connection Type was "Automatic Configuration-DHCP"
2) Changed Network Setup to "DHCP Server-DISABLED"
3) Turned off the Firewall settings in Security (not sure if this is necessary)
4) Changed the Operating Mode from "GATEWAY" to "ROUTER"
5)Changed the SSID to "LinksysG_ONLY" or something like that
After each one of these steps, I had to save the configuration, thru the Linksys browser interface-which blows.
6) Finally, I changed the Local IP Address of the Linksys from 192.168.1.1 to 10.0.1.251 (thanks to Henry B. for that)
7) And....I no longer had access to the Linksys at all! This stumped me for a while, until...
8) I checked my Ethernet settings (in System Preferences/Network): 192.168.1.1 was set as default router address. But my Router (at least for configuration purposes) was now 10.0.1.251, so it could no longer find it.
9) So I added a new Ethernet port (using the "+" sign), called it Ethernet-Linksys. Set it to Manual. Put in an IP of 10.0.1.250, and a Router IP of 10.0.1.251.
10) I got access to the Linksys setup page again! (Note: I'm sure there is an easier way to do this, but this is how I got mine to work )
11) I set up WPA security again, set it to an unused channel (2 in my case), mixed b/g network.
12) Finally, I moved the ethernet cable from my MacBook directly to one of the ethernet ports on the Time Capsule. I did NOT hook up the other end to the WAN on the Linksys (which for some reason I had done 100 times before) I left it in one of the 4 ethernet ports on the Linksys. Repeat, the WAN (ethernet) port remains empty.
13) I then turned Airport back on the MacBook, connected to "LinksysG_ONLY", and...I was online. And everything seems to work.

Hi kjk et al,
I've been searching the boards for something like what you have described in such nice detail. Before Time Capsule, I used a Netgear g router connected to the cable modem and an older Apple base station connected to the Netgear as a bridge. I removed the Netgear and set up my Time Capsule as the primary. The newer computers in my network can access the Time Capsule, but the old Dell with a 802.11g wireless card cannot. I don't remember seeing where I could access TC to change a setting of "N only" or b/g, but I am guessing that it is running N.
I tried to follow the steps you used for Linksys. The pre-step 1 thing, resetting it "10 times to get it to work" - how do you know when it is really reset? With Netgear plugged into electricity, I stuck a paper clip into the hole labeled on the diagram as "restore factory settings" and watched the color of the IO icon change from green to amber to green. I did it again for good measure.
I plugged ethernet from PowerBook G4 into Netgear not-WAN ethernet ports (like your MacBook to Linksys). I disabled Airport. Using Safari, I logged into 192.168.0.1 and got to the Netgear SmartWizard configuration assistant. It says, "No Internet Connection Detected. Please check the connections to the Internet WAN port and cable/DSL modem" - so I looked at your instructions but see no mention of connecting the router to the modem.
Trying to follow your numbered steps...
1. In SysPrefs: Network, Location showed Automatic, Configure showed Using DHCP.
2. I don't see an option in Network to "DHCP Server-DISABLED", but I can choose Configure: OFF. I clicked Apply but browser still gives same message.
I don't know how to continue the steps.
