intel 6300 max speeds

just kinda curious as to what kind of speeds people are getting with the intel 6300 wi-fi adapter (i have a 8170, but i don't think that should play a great role). i have a dlink dir-655 router, and according to the software inssider i should be able to max out at 300 Mbps. i was able to get 270 Mbps briefly, but it seems that i'm usually getting 130 Mbps with the same router and adapter settings. is it an issue with the 6300 (i've also installed the latest 6300 driver) that's in my 8170 or with the router?

 

You may need to change a few settings. Go to start > control panel > netowrk and sharing center > change adapter settings > right click the 6300, properties > configure > advanced. Make sure that the channel width is set to auto, not 20Mhz and that transmit power is set to maximum.

It should max out at the full 300Mbps that way if that's the max your router can do*

*Assuming you're relatively close by, as attenuation at range will drop your signal strength a bit.

 

actually that card is supposed to allow for up to 450Mb/s, and just so you know there are 8 bits(little b) in one Byte(big B), also you can only get that speed when you are really close to the router, like 15 feet away. currently on my 6230 im getting exactly 300Mb/s while im 15 feet away from my router, it does fluctuate though and honestly unless you are transferring files locally on the network between computers it wont make a difference as long as it doesn't dip under 30Mb/s.

Also no one else in my house uses wireless n and we have a router that supports 5.2ghz and 2.4ghz, i changed the device settings so that it preferred the 5.2ghz and now its just almost always 300Mb/s. To do this right click the wifi icon on the taskbar, then click "open network and sharing center". then on the left side of the new window click change adapter settings, and then right click on the icon that says intel centrino advanced n. click properties, then click configure and click on the advanced tab. in the list click preferred band, and under where it says value select prefer 5.2ghz. and thats it.

 

From how I read it, his router only supports a maximum of 300Mbps. Only a handful of new routers do 450Mbps yet. (It also looks to only support 2.4ghz, not dual band 2.4 and 5.2)

2.4ghz is a more crowded frequency, but has better range. 5.2ghz is an emptier frequency (meaning less interference), but it's also shorter range due to attenuation in the signal.

You're right though, for small home networks 300Mbps versus 270Mbps is pretty insignificant and 5.4Ghz will generally offer better speeds overall.

 

you're basically right (i think). the dir-655 is rated at 300 Mbps since it is single-band (2.4 GHz) though it is 802.11n. i'd be happy to get a solid 270 Mbps all the time, but though i've gotten that speed before for short periods of time, it seems that the usual speed is 130 Mbps, which i guess is OK for most practical purposes but still it irks me that I can't get close to rated speed for more than a short time (curiously enough usually at the same time about 11:00 pm).

 

did u try setting it to prefer 2.4ghz?

 

i think i've tried all possible combinations of settings over the past couple of days, including the one that malibal #2 suggested. i guess i'll have to resign myself to below rated speed performance, unless i splurge for a new router.

 

Doesn't seem like anyone asked but how far away from the router are you? Do you go really close and still only get 130Mbps? I have a 6300 also and you can normally get excellent link rates but it also depends on your area and the router as well.

 

normally i'm about 25 ft from the router, but on the floor above it. but just now for the heck of it, i moved my laptop to within 5 ft directly away from the router. same 130 Mbps speed (at this distance, i ran inssider and got -25 for the RSSI, and the only other device detected had an RSSI of about -100, so there didn't seem to be much interference). again i have gotten 270 Mbps, even 300 Mbps in my normal location, but only for brief times.

 

You need 40MHz channel width to achieve 300mbps. Auto settings does the job but it automatically reverts to 20MHz when neighboring network is detected- this may be the case.
You should either change a channel to a free and preferably non-overlapping one or force 40MHz (if this option is available).

Also make sure that Intel is set to 40MHz (advanced driver settings available via device manager)

 

I haven't looked at the DIR specification.

As download stated before...

If it is running N Standard, not draft. Running wide channel width would do nothing if your channel overlaps an active neighboring channel, it will automatically but it back down to 20 Mhz channel width which gives 130/144 Mbits link max.

Only noncompliant N Wireless AP allow the option to force the wide channel width.

 

just checked, and both the dir-655 setup and my intel 6300 advanced do not allow me to force a channel width of 40 MHz; the only option is auto (20/40 MHz), so i guess that's that. i was thinking of trying a later firmware for the dir-655 (i'm at firmware 1.20 while i think the latest may be 1.33), but it seems that dlink does not have a great reputation for their firmware. anybody have experience with the latest firmware for the 655? at least, with the current setup it's pretty reliable.

 

I just finished modding my Router recently.
It is a very high performance router now.
Running OpenWRT.
I have written it on my blog but not sure if it is allowed to link here.
Anyone interested?
