Computer won't recognize 5ghz router (computer has 5ghz), windows 7

[nuphase]

My question is I have a computer with 2.4ghz as well as 5ghz, my router is a dual band 2.4 and 5ghz wireless n and no matter what I do my computer will not recognize the 5ghz network.

Background info: I have read through many forums and tried many different solutions none of which seem to work. My computer is 2 weeks old (hp). I have gone into device manager and clicked on the network card, properties, and advanced tab to discover my computer does support both 5ghz and 2.4ghz, as well both are enabled. My router is the wrt601n linksys dual band N wireless router. I have tried every setting possible with that router including : mixed, n only, a only, 20 or 40 all different widths and no matter what combination my computer will only pick up the 2.4ghz. Both drivers/software for my computer and router are up to date with the lastest. I have also tried close to and far away, distance and range are not issues either. It's becoming a major issue not having both bands working because we having gaming equiptment that when somebody is playing it kicks the other person off of the internet entirely! I am at a loss here on what to do please help!!!

Go into your cards'
'Computer management' > 'Device Manager' > right click on your wireless card > 'properties' menu > 'advanced'

Check that 2.4/5ghz is set up for your correct country band! (UK = 1-13)

To turn on Dual band wireless 'n'
My linksys 2.4/5 pci card has a menu item called "Multimedia Gaming environment" > 'enable'

This enables dual band - top speed @ 300!

I'm not sure why you can't get the 5GHz band to work for you, maybe neo's suggestion might help with that.

It might help your situation to know which channels your neighbors are using so you can find one that isn't being used. This software from Xirrus will show you all the channels being used in your area so you can pick the right one.

Important - forgot to add . . . . .

once on wireless 'N' dual band @300 ALL connecting computers have to be at that setting or they will not work!

ie you cannot connect with a wireless 'g' card - whereas you can connect with mixed wireless b/g/n @150 single band



"no matter what combination my computer will only pick up the 2.4ghz"
This is the single band 'n' connection that allows 'B' & 'G' cards to work with 'N' cards on same wavelength.

Thank you so much for your replies! Chev 65, I have been aware that sometimes neighbours may cause issues with interference that way but I am out in the country-rural area and can only pick up one neighbours wifi, Im sure the rest of the neghbours arent even sure what wifi is lol. Thank you however because that is one thing I forgot to mention that I had looked into. Neo, I never even thought to make sure about the right country band, I never even dawned on me that, that is what the value means, my question however is how do I know what my country band is. I have googled it a little bit but cant seem to find anything. (canada). Also I had noticed that my 2.4ghz country band and my 5ghz country band are different values. My 2.4 is 1-11 and my 5 is 36-165. Should they be the same perhaps, because I know that my 2.4 is visible. However there is no value of 1-11 for country band on the 5ghz values...I did enable the gaming as well. Thanks again for all your help!!!

 

[neo101]

The software is clever enough to find country band automatically now so prob right in both bands for Canada. 1-11 is correct as you can see here. Your 5ghz band is also correct (same as USA 36-165). Are 2.4/5ghz bands set the same (1-11 + 36-165) in router?

Can you give make/model of wireless card
Exact serial/model of Packard

If you have a pre-'n' draft card it prob won't work @ wireless 'n' @300 dual band

If you have linksys card, you need the wmp600series.
The 300series is draft pre-'n' so you're stuffed - chip can't cope!

Couple of excerpts from linksys comments

Re: WMP300N Vs WMP600N - Cisco Home Community

WMP300N -
1. Standards : IEEE 802.11b, IEEE 802.11g, Draft IEEE 802.11n, PCI 2.3
2. Security Key Bits : Up to 256-bit wireless encryption
3. Certification : FCC
4. Does not support Windows Vista 64 bit...
5. Not Dual Band

WMP600N -
1. Standards : IEEE 802.11a/b/g, IEEE 802.11n Draft 2.0
2. Security Key Bits : Up to 128-bit wireless encryption
3. Certification : FCC, UL, IC, CE, RoHS, Wi-Fi a/b/g/n Draft 2.0
4. Does support Windows Vista 64 bit...
5. Dual Band

"When you compare WMP300N and WMP600N ,you should go with WMP600N

However, both the WUSB300N anfd WUSB600N "do not" work well with the Linksys drivers / software. Neither adapters have the internal chips "made" directly by Linksys. These are "licensed" from another company. WUSB300N was from Marvel and the WUSB600N v1 is from Ralink.

Use the WSUB600N v1 with the Ralink RT2870 drivers. These Ralink drivers are newer."

Try setting the 5ghz channel to a channel like 161(?) manually in the router (ie - not left on auto channel)

See if wireless card picks it up.
(Turn off your computer firewall & test)

Sorry for the delay in getting back on here. Still have not been able to get the 5ghz to work. tried setting the channels manually and still nothing. The HP is hpe-341f and the wireless card the only info I know how to find is through the device manager and it says 802.11n wireless LAN card. If there is another way to get more exact infor let me know and I will definitely look it up. Thanmk you again!!!!!

 

[neo101]

Thawt u were sorted!

Is this it? Same model number?

HP Pavilion Elite HPE-341f Desktop PC Product Specifications HP Pavilion Elite HPE-341f Desktop PC - HP technical support (Finland - English)

Obviously find english/french Canada website!

I can only see it mention 'n' - see if there is a Wireless driver update on the HP website for your card. You would have to register first probably with all your details that came in the box with 'puta.

There might be a 64bit problem, as in no finished driver (they craftily don't tell you about) or the card is incompatible with dual band/64bit due to onboard chip limitations.

Why don't u ask H.P. for some free advice - you must be under warranty etc

Check if there is a 'firmware' update for your linksys too, on Cisco site. Again you need to register with linksys/cisco to get hold of that sort of stuff usually.

If the statement above is true then there is no way you could be kicked off your own network. You should be having no problems using the 2.4Ghz band in this case because it's impossible to have a channel crosover problem if there are no neighbors in range.

In fact the 5Ghz band is really meant to be used if all the 2.4Ghz channels are being used in your area and you have no other means for a good connection. In fact the 2.4Ghz band usually works better than the 5Ghz band.

So something else is kicking you offline but it has nothing to do with using the 2.4Ghz band. You definately need to update your firmware if you havn't already.

You also asked about this> Also I had noticed that my 2.4ghz country band and my 5ghz country band are different values. My 2.4 is 1-11 and my 5 is 36-165.

Those are just different channels of the two different bands, they are not intended to match up.

connecting into 2.4 and 5.0 ghz modem channels

Regarding some people's inability to log onto the 5.0 ghz channel, what I've noticed here at my home is that only the 32 bit machines can connect to the high speed. The 64's will not !! Now, why, I don't know. Maybe someone out there can explain why. It's a darn shame, because the slower machines end up being faster to the internet than the faster 64 bit machines. When I check the internet speeds, I get 175 MHz with the 32 bit machines and 60 MHz on the 64 bit machines. I'm using Comcast's high speed internet.

Laptops not recognizing 5.0 ghz wireless channels

My Lenovo laptops don't recognize the 5 ghz wireless channel, but my son's computer does. I want to be able to select the 5 ghz channel because my new security cameras knock my laptops off of the internet when the cameras are on. They use the 2.4 ghz channel and take too much of it for my laptops to stay connected. Why can't my laptops see the 5 ghz wireless channel?

Malinda,

hold down the WINDOWS key, and hit R
in the 'run' command type devmgmt.msc and hit OK
this will bring up your device manager
look for Network Adapters, then click the arrow to the left of Network Adapters to open this view
Look for your Wireless adapter/Wifi
Mine, for example, looks like : 802.11n Wireless Lan Card
You'll see 802.11 on nearly any card, but, what letters follow it?

These letters will tell us if the device is capable of viewing the 5.0 band (typically, you'll want to see an 'a' along with any other letters). If the pre-installed WiFi card is not capable of viewing the 5.0 band, you'll need to purchase something like a USB Dual Band adapter for that device.
