PostPosted: Tue Jan 05, 2010 5:14 pm    Post subject: Wireless N and 5.0 bandwidth

I have googled this question every way I can think of and have asked those I know who are fairly technologically savvy and have yet to get a definitive answer to my question. So I am here at my old, never fails, standby - Lockergnome.

Without giving you the whole story (unless you ask for it) I need to know if all wireless N adapters are capable of supporting/reading a 5.0 bandwidth. Confused

I have one in my new blu ray and it failed to find the 5.0 frequency being broadcast by my new Simultaneous Dual Band Linksys 610N v.2 router. It found the 2.4 no problem but not the 5.0.

Both frequency's were set up with unique SSID's.

Running Win XP on wired PC and Vist Ultimate 64 on wireless PC. Don't know why this would matter since I was able to install the hardware (router) with no problem,,,,,, mostly... Wink

As of right now I have the router back in my car and ready to go back to the store. Neither LG tech support (for the Blu Ray) nor Linksys tech support were able to help with this or give me an answer. Can u believe that? Laughing

Someone with the same wireless router and the same problem, though a different version of firmware
http://forums.linksysbycisco.com/linksys/board/message?board.id=Wirele...Routers
he has not responded if the "fix" worked.

Do the computers have n capability? If so, can they use the router?

I'm trying to figure out if the problem is with the router or the bluray device. At this point, it could be either device.

Thanks for the reply zlim and for the referral. The fact that that guy's G adapter in his old laptop, as he described it, could find and read the 5.0 bandwidth suggests to me that any N card should be able to do the same thing.

The instructions he was given by "dibbler" seem a bit much to me. Nobody should be left with having to go through all those gyrations just to get a system to work as designed. Sorta like going on top of the house to adjust the tv antenna. Or kinda reminds of win3.1 and 95 days and trying to install those 28/56K modems and the like. I can't imagine Linksys selling many routers that involve all those machinations for it's buyers. A lot of returns would be in the making. I know I'm not going there.

But thanx again for your response.

Well the blu ray reads the 2.4 just fine, so it seems kinda quirky to me that it would not be able to read 5.0 if it was designed to do so.

I'm not sure how Blu Ray enters into all this, but I do have an Intellinet Wireless N router connected to my Motorola cable modem.

I transmit wireless internet to another building about 300' away with perfect clarity.
That PC also has an Intellinet Wireless N lan card installed.

My connection speed to my ISP is 5 meg.
But the connection speed between the N router and the wireless PC is about 320meg. I don't understand why any type N wireless connection would have any problem with a mere 5 meg ISP connection. Question Question

Hello,

Not all 802.11n devices support 5.0GHz frequency range. Many of them are limited to the 2.4GHz frequency range. 802.11n devices which support both ranges will be labeled as dual-band or simultaneous dual-band devices. Also, they will be compatible with the older 802.11a standard, which operates solely in the 5.0GHz range.

Regards,

Thanx for the replies. You are evidently right goretsky. But what really baffles me is that nothing I have read and I have googled and read and googled some more and read and no one states this clearly. To read everything I have read on this matter one would be left to assume that if you have a wireless N adapter, it will support a 5.0 bandwidth.

Doc, my blu ray has a wireless N adapter and I was simply looking to connect with a frequency that would naturally have (so I'm told, depending on ones other devices, neighborhood etc...) less likelihood for interruption from other devices using the same frequency, such as a 2.4 would tend to have. A continuous uninterrupted wireless stream for movies streaming directly from the internet.

I.E. VUDU.....

Question: If I stick a usb dual band wireless N adapter into the front usb port on my bluray should that work with a dual band router. Leaving the already existing wireless N adapter in the unit.

Hello,

If you are in a store, you can look for the Wi-Fi Alliance logo on the box of the product you are interested. It shows whether the device supports 802.11a, b, g and/or n.

I am not sure which brand and model of Blu-ray player you have, but with the model I have (a Samsung BD-P1590), it has to to be a specific Samsung-branded Wi-Fi USB adapter. Price was about $70.00 retail, the last time I looked for one.

Thanks goretsky. Mine is an Lg BD390. I got out the drill and went hard wire last night (that 30 minute project turned into about 2 hours and a bloodied hand Mad ). To be honest I was getting a pretty impressive wireless connect with only a few re-buffs during my viewing of movies but I figure the cost of a hard wire, about $25, is a lot cheaper than continuing to try and find and spend money on routers and adapters.

After doing a hard wire I still get buffering on my movie streaming which suggests to me that the bottleneck must be from the internet to/through the modem/router, not from the modem/router to the blu ray. Does this make sense and how might I improve that?

Hello,

Can you describe the topology (layout) of your network in more detail? With that information, it might be easier to determine where bottlenecks might be located.

Cable to modem, modem to router, hard wire from router to desktop, hard wire to vonage phone modem, wireless to desktop in another room, wireless/hard wire to blu ray.

I hope that is kinda what you were asking for goretsky.

Hello,

If you still have a wireless connection established to your Blu-ray player, try disabling it so only the cabled Ethernet connection is present. Does that make any difference?

That was my first thought but when I go into my internet settings on the bluray I don't see that it gives me that option. It allows me to choose "wired" or "wireless" for my connection but not to disable either. May be something in the manual I'll check. If so I'll let you know. Thanks Goretskey.

What I have noticed thus far is it initially seems confused about it's connection and doesn't want to start a movie, but when the movie does start it appears, so far anyhow, to stay connected for duration with no buffering.
