intel 2915abg cant see 5ghz a networks

as above, laptop can see g netwoks fine but it cant see anything in 5ghz. what could be the problem because i have no idea.

could it be the internal aerials dont work at all for 5ghz?

 

First question, is there a 5GHz network in range, i'm assuming yes, but eh doesn't hurt to ask as some routers aren't simultaneous dual band, but can only transmit on one at a time.

Moving on, is your 5GHz network set to wireless N only, do you have other devices that can see the 5GHz network?

 

there is a network, and no it wasnt set to N only. it was wpa2 only if that matters but i dont see why it should

 

Does the router support 802.11a standard in the first place?

What is the router's make and model?

 

5GHz also doesn't make it as far as 2.4GHz, so maybe you're just out of range.

 

thread bump.

i think i had given up trying previously but am encountering issues again as is. to answer the q's abouve, router is a WNDR4500 and yes 5ghz is most certainly in range.

 

2915ABG is one lousy card and I'm being nice here. I've *never* managed to get any of them to work in the 5GHz range at proper "A" speed.

No, that's most definitely not the case. Antennae have absolutely nothing to do with your machine's ability to "see" the network.

Go under the card's properties or advanced settings in the Device Manager and try playing with the settings a bit. You might get lucky.

OK - Intel 2915abg does not support 802.11n even if it's on 5GHz band. You have to set up your router 5GHz radio to "up to 54mbps" to make the router work as 802.11a.

 

really??? i wonder if thats why i think that card was causing network troubles.

hmmm, i wish i could just replace the card but ive never found an N capable card for mini pci that would fit. oh well. thanks for the input anyway guys.

 

Have you investigated whether the TP-LINK TL-WN861N Wireless N300 Mini PCI Adapter would work in your unit?

It may only be 2.4GHZ but it's 300Mbps N

Amazon.com: TP-LINK TL-WN861N Wireless N300 Mini PCI Adapter

while i do appreciate the effort that card doesnt physically fit. i dont know if its slightly out of spec size wise but there is a cable attachment in the way. i did buy one of them, that was how i found out.

 

Another "N" option...

BTW, what laptop are we discussing here to begin with?

Good luck.

 

ooooh, ordered one. much thanks, i was not aware of its existance

the laptop is an old Packard Bell Easynote. http://www.amazon.co.uk/PACKARD-EasyNote-MZ36-R-017-HardDrive-Radeon/dp/B003SDEMPU that would pretty much seem to be it. ram was instantly upgraded, hdd was too later. oh and it runs win7 now. (the laptop now just lives in the kitchen to run itunes and play podcasts.)

 

Wow, I haven't seen one of those connectors since 2005 when I had a Toshiba M40. I'm surprised they still make them.

 

so am i, when the tplink one didnt do id pretty much gave up getting an N card. hopefully it will let me set the router back to n and not bugger it.

side note, netgear routers, once good but so not any more.

 

hey, just to say, it came today and it works!!!

the 2.4 and 5ghz both work and it connected at "243" mbit and i can stop tho router doing g only at 2.4. thank you very much for pointing that card out to me, yey!!!

 

You're very welcome - good to hear that you're happy with the upgrade - enjoy!
