A Question about DIR-825 + DAP-1522 + DWA-160

[Viruzz_IL]

Hello,
I want to minimize the amount of wires in my room so im moving to wireless, network and audio (Bluetooth headphones and such).

I purchased DIR-825 router + DAP-1522 Bridge + DWA-160 adapter

I have a couple of questions if please if you don’t mind: ( the distance between router and Wireless adapter and bridge is 2 meter in same room, both on opposite sides of one desk)

1. I purchased adapter for my PC and Bridge for my xbox 360 and PS3, now all these 3 are located on same desk and I never use all 3 together, it will be PC+XBOX or PC+PS3
My question is can I use DAP1522 Bridge with all these 3 devices or it will be better to use PC with DWA160 adapter and Bridge with consoles only?
is there any benefit of dividing them? Or maybe I should eBay the DWA-160 adapter and keep everything connected to wireless bridge?

2. currently I disabled 2.4Ghz band on all devices and everything works on 5Ghz/40mhz, the router comes with 2 antennas, so by disabling one band will it free more resources / bandwidth to another one?


3. there is an article on this site about how bad is to use mixed mode wireless, that it affects N speed.
So if I use 5Ghz as N only and 2.4Ghz as B only (for my PSP) will it affect the speed of 5Ghz N?


I hope its not too many questions, thank you, Benny.

Frankly, I think you wasted your money with all this gear just to get rid of a few Ethernet cables, especially since it is all sitting on one desk top. You may even get reduced performance, since I have seen overloading issues with draft 11n products when router and client are too close together.

Answers:
1. You can use the DAP1522 for both devices.

2. The # of antennas is irrelevant. You aren't getting any performance benefit by not using 2.4 GHz.

3. I suggest you go back and re-read the article. If N devices are associated with one radio and b/g devices are associated with a second radio, then you are not running a mixed WLAN.

I have to agree with Tim on this one.. If everything is on one desk or in the same room you would be better off using Cat 5e or Cat 6 (cuts down on EMI/EMF). If you were using these equipment throughout the house then it would be a better investment. Today you have desks that can hide all the LAN cables, power and coax (if needed) so you end up with a neat wire free from view management system.

Thank you all for repaly!

i used Cat6 before but my router was only 100Mb

What i mean by Mixing is that if i use one antenna for 5Ghz N and another for 2.4Ghz b/g, wont it reduce my N performance?
I mean otherwise N could use both antennas?

I expected to get 250+ because its same room and im the only one with 5Ghz router but the speed is fluctuating, from 270 to 108 and i dont understand why.. maybe better to force 200mbs (should be enough for HD video)?

any tips to improve the speed? I ordered TERK WF-D DUAL BAND HIGH GAIN DIRECTIONAL ANTENNA (sorry for caps, copy/paste)


I disabled WISH, because i have 8Mb ADSL and i use Usenet service, usually i download at full speed but after upgrading the router my Usenet speed was weird it was going up and down, up and down like yo yo


And again, thank you

When they say 300MB/s for N it's really 150MB/s or less depends on the Router reports. Don't go by what you see in Windows OS or Wireless Third Party Programs.

Wireless N

300MB/s = 150mbps
270MB/s = 135mbps
260MB/s = 130mbps
240MB/s = 120mbps
130MB/s = 65mbps
120MB/s = 60Mbps

To the left is what the chipset can handle and to the right is real time speeds but these can vary by -20mbps in the router for N as it reports current speed measurements.

Wired 1000mbps

600+mbps

Wired 100mbps

60+mbps always 40% lower

Wired 10mbps

6+mbps

Huh? 100 Mbps Ethernet is fine for what you are trying to do.

What i mean by Mixing is that if i use one antenna for 5Ghz N and another for 2.4Ghz b/g, wont it reduce my N performance?
I mean otherwise N could use both antennas?

It doesn't work that way. There are actually separate antennas for both bands and both are used.

I expected to get 250+ because its same room and im the only one with 5Ghz router but the speed is fluctuating, from 270 to 108 and i dont understand why.. maybe better to force 200mbs (should be enough for HD video)?

You will not achieve speeds above 100 Mbps with most draft 11n gear. The 270, 300 Mbps rates you see quoted are maximum bit rates, before protocol and retransmission overhead is applied. Usable draft 11n rates are more in the 40 - 80 Mbps range depending on products used.

Just use Ethernet.

Thanks you people helped me a lot..
