Dual band n wireless router optimization

Just configured a new wireless router. Would like to input on optimizing for ATV2.
It is 5 and 2.4ghz simultaneous bands. Router will be within 30 feet of Atv2.
Where should i begin?

My set up is this with the same dual band set up..
I have the 5 ghz looking at all of my atvs(3)of them plus the channels are set higher than my neighbors.
All other laptops in my house are looking at the 2.4 ghz Connection and not the 5 ghz.
So I have split the signals so the atvs run on a dedicated line without problems.
Are the atvs on the 5ghz band set on n band only? Besides channel settings any other. Do you have wmm enabled.
Thanks.

Will my Lenovo W510 WiFi work with a 2.4:5Ghz Netgear N600 WNDR3400 dual-band home broadband router?

My first post ever ... so please be gentle with me.
BACKGROUND:
1. I'm considering a new router to replace my Linksys WRT54G.
2. The Netgear N600 WNDR3400 dual-band home broadband router has a simultaneous 2.4Ghz & 5Ghz AP capability.
3. While I know my Lenovo W510 WiFi works fine at 2.4 Ghz (802.11G), my question is:

As an update, I bought the WNDR3400v2 router and am supremely disappointed with its lack of power - but - the Lenovo W510 DOES work perfectly fine connecting to both the 2.4Ghz and 5Ghz radios.
The problem is the signal strength only twenty feet away up one floor is dismal (as compared to what it was with the ancient Linksys WRT54G for example).
What bothers me is that Netgear goes to great lengths to hide the power output of the radio so I 'suspect' that it is anemic and I don't (yet anyway) suspect the radio on the W510 laptop. Netgear support would only tell me the EIRP at 2.4GHz is 20dBm, and at 5GHz it's double that. So I can only assume the power output from that. If I assume a 5dBi antenna gain for both frequencies, that results in a power output guesstimate of 15dBm (32mW) at 2.4GHz and double that at, i.e., 18dBm or 64mW, at 5GHz.
The other side of the equation, of course, is the power & gain of the W510 radio & antenna.
Do we have specs for the W510 power output & antenna gain (e.g., a typical laptop is about 50mW (roughly 15 to 18 dBm) pushed into an antenna with a gain of about 1/2 dBi to about 1 dBi at best, regardless of what the specification sheet intimates)?

5.8 Multi-Band N Wireless Router?

Does Cisco offer a Small Business 5.8 GHZ muli-band N wireless router? I was looking at putting a client on the RV180W, but it looks like it's only a 2.4GHZ single-band N router. My client was wanting a 5.8 GHZ multi-band N router for his small business.
Thanks!

You're correct. 5 GHZ is what I meant. I was thinking of the older cordless phones before DECT. :-)
To re-phrase my question...

DrayTek Vigor 2750Vn Dual-Band VDSL Wireless Fibre...

As anyone used this router before?, While reading up on it, It as the VDSL modem built in so you can get rid of the openreach modem and bt hub and just used this...
Just wondering as anyone delt with this company and use this router with BT infinity as it makes alot of sense of just getting rid two items and just having router doing everything which takes up less space

Hi
I have a Draytek2850. It is the base model without wireless.
It is a sturdy box and it does away with the Openreach + HH3 which can clutter up the desk.
Connection is good and comes up faster than the HH3.
There is only one slight drawback in that my Draytek syncs slightly lower than the Openreach modem. This tends to give a drop of about 1-2mbits on the download. Not an issue if you get a really good speed if you are sitting on top of the cabinet!
Hope that helps

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.

IMac connecting to N channel on a dual band router but only at 54mps

I have an iMac late 2009 model connected wireless to a dual band Netgear WNDR3300 router. My problem is it only connects at 54mps on the N channel and that is with the router placed 2 meters from the computer. My PC laptop similarly placed connects at 270mps no problem. When I option click on the Airport Utility in the menu bar it tells me I'm in 802.11n mode on channel 149(5ghz). When I first got the iMac it connected easily at 270mps. So something has happened. Has anyone had a similar problem?

I had a similar problem with a NetGear DualBand DGND3300v2, the issue in the end was security.
I was initially trying to use WPA-PSK and getting this exact same issue, with my Mac, stuck at 54Mbps on the 5GHz band, disabling the security allowed me to connect at 'up to 270' but obviously not secure, so moving up the security options tried WEP, this also allowed 'up to 270'. WPA-PSK was no go, so I went to and am using WPA2-PSK and it works fine, sometimes I get a connection of 300Mbps.
So give it a try, let me know of it works for you...

E2000 dual band question for a noob

Can the e2000 use 2.4ghz for my laptop but use 5ghz for my wife's laptop.I know the band is selectable but what I am trying to find out is can I tell the router to use a specific band for each laptop.
Solved!
Go to Solution.

The E2000 is a dual band single radio router. You can select either 2.4 GHz or 5 GHz. But as it is single radio only you can only operate on one frequency but not both at the same time.

Time Capsule 2TB vs. Netgear WNDR3300 RangeMax Dual Band Wireless Router

Hey everyone, I just bought the Time Capsule 2TB since I was running out of space at home and wanted a solution for both PC and MAC machines. Upon installation I learned that the TC can actually be my Wireless Router! Right? For some reason I never knew it could do this - I thought it could just be a wireless harddrive.
Ok, so I already had a wireless router (the Netgear WNDR3300 RangeMax Dual Band Wireless Router). So my questions are the following:
1) Is the TC a completely safe and equal replacement for the Netgear Wireless Router that I have?
2) Currently the TC is setup as a wireless HD on my network (where the Netgear is the router) and the transfer speeds I am seeing are pretty darn slow! I am assuming it is because the data needs to go from LAPTOP -> Router -> TC. Right? So my question is, if the TC is setup as the actual wireless router, then would the data transfers be faster? Since I would only have to go from LAPTOP -> TC to store the data.
One more side question regarding the TC and connecting a printer:
3) If the printer has scanning capabilities, then where does this scanned document file go when the printer is connected to the TC ?
Thanks for your help!
John

John, welcome to the discussions!
I can provide a few thoughts and hopefully, others will as well.
"1) Is the TC a completely safe and equal replacement for the Netgear Wireless Router that I have?"
It appears to offer essentially the same features and performance at a glance. If you are using ethernet devices, the TC has 3 LAN ports, while there are 4 on the Netgear.
"So my question is, if the TC is setup as the actual wireless router, then would the data transfers be faster?"
I think it will be about the same. You could of course hook up the TC and try it, but I doubt that you would notice any measurable difference.
"3) If the printer has scanning capabilities, then where does this scanned document file go when the printer is connected to the TC ?"
Assuming that your printer is compatible with the TC you will be able to print, but advanced functions such as copying, scanning, maintenance, etc. will not work. You will need to connect your all-in-one directly to your computer if you need these other services.

Wireless Expander WRE54G and Dual Band router WRT610N

I used to have a band G-type network with a Linksys Router and a Wireless Expander WRE54G. It worked fine.
Now I have a WRT610 N Dual Band router. I am trying to connect the WRE54G to the netowrk (using the G-band of course) but it doesn't work. Runnig the Setup utility from the CD (og the Range Expander) ends in a "Site survey" which terminates with an error "Site survey fail". Maybe the installation program is not able to handle the WRT610N.
Any suggestions?

Press and hold the reset button on WRE for 30 seconds...Release the reset button...Unplug the power cable from your Expander, wait for 30 seconds and re-connect the power cable...
Connect your Expander to a computer, click on the Start button >>> Settings >>> Control Panel >>> Network Connections - Right click on the icon for Local area connection and go to properties- On the 'General' tab select 'Internet Protocol TCP/IP' and click on the Properties button- Select 'Use the following IP address'- Provide IP Address - 192.168.1.5, Subnet Mask - 255.255.255.0...Click on Ok button to Save and Click on "Close" on main Properties window...
Now open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.240. Leave the Username blank & in Password use admin in lower case...It should open your Expander set-up...
Once you get to the set-up page,change the Expander Settings...While changing the Expander settings you have to make sure that the Wireless Settings(SSID/Network Name and WEP/WPA Key) are identical on both the devices(Router and Expander)...Also make sure to change the Expander's default IP to match your network and Gateway Address should be your Router's address...ex.Expander's IP Address : 192.168.1.240(assuming your router's default IP Address is 192.168.1.1),Subnet Mask : 255.255.255.0, Default Gateway : 192.168.1.1...
After configuring the Expander you should disconnect it from the Computer and go into Local Area Connection TCP/IP Properties and set it back to Obtain IP Address Automatically...Disconnect the Expander from the computer and power cycle both the devices(Expander and Router) ...Your Expander should be configured...

NetGear N600 Wireless Dual Band Router WNDR 3400

Hi all,
My neighbor and I (Sarah) both live on the second floor of a circa 1820 house.
Wi-fi is included in our rent.
Neither of us can connect to the house's NetGear N600 Wireless Dual Band Router (which is on the first floor) with our MacBooks (both purchased new earlier this year and both running Mac OS 10.7).
We can connect to the network with our iPhones, iPads and Windows Notebooks.
But when we try to connect with our MacBooks, we get a connection timeout error.
Any help would be mucho appreciated.
Mike

This is a part of the larger MacBook Pro connectivity issue. There are several related threads dealing with the MBP's networking problems. If your unit is suffering from this type of difficulty, good luck ... (or a long ethernet cable)
(PS Everybody please make noise on this one so apple comes up with a solution.)

Cisco Wireless - N E2500 Dual Band Router and Hide SSID

Hi,
I have tried to hide my SSID by dis-enabling The SSID broadcasts of first one then the other band.
Once I dis-enabled the SSID broadcast of the last band my laptop, which has the wireless card, would lose connection to the internet on reboot.
I have read somewhere but now cannot find the article, that one can hide ones SSID but that it requires some work to connect to a network that is no longer broadcasting.
Anyone have knowledge on how to go about this or maybe they could point me to a resource that discusses how to set this up....thanks.
Tom.
Solved!
Go to Solution.

Thanks Exotic Fish ... Do you no anything about the Dual Band.
I understand that we can only use one band at a time ... that is great ....so I have the 2.4Ghz connecting automatically.
When does the 5Ghz kick in ... if it does ... or do you have to manually connect to it?
Thanks.
Tom.

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.
