New laptop - WI-FI N only connects @ 72mbps - DW1501

Hi there

I have the same problem with my  DW1510 Wireless N WI-FI card , I also brought my misses a HP laptop and that is working flawless great wireless speeds.

My router is DIR-855 router (D-Link)

When I Connect my speed is 72mbps and then drops to 65mpbs and transfer are so slow it as brought me here and to search google and I see reports of this wireless card not performing the way it should be..please advise i have not had the laptop more than 4 days...

thanks Day

I also have this same issue with a new Inspiron N7010. It has the DW1510 wireless mini-card also.

My router is the D-Link DIR655 Extreme Gigabit Router.

Connection speeds for two other laptops is quite good:  Asus Netbook connects at 150 mbps and Sony Viao at 117 mbps.

Hopefully a Dell guru will see this thread and offer a solution.

Thanks in advance.

Well it took almost three hours on the phone to India but because I'm stubborn and won't take no for an answer Dell will

be sending a technician out to replace my wireless adapter also. Hopefully the Intel 6200 will do the trick.

Thats great news.....keep all of us informed and i will do likewise...Goodluck

Hi Guys

Dell have been out for this morning and replaced my wireless card with the Intel 6200 and results are what I'm used to 270mbps - 300mbps...awsome speeds :)

.

Just a big thanks to do Dell for there great support.....one happy customer....Day

That's great news!! I still haven't heard when I'll be seeing a tech but hope it's soon.

Day, how are you getting 270mbps?  What your router?

Tech just left and my speeds have basically doubled to 144 mbps.

Originally I was using a D-Link DIR655 Extreme Gigabit router but I've changed to a Netgear WNR3500L. This change increase my speed to 72 from the original 65 mbps.

The change to the Intel 6200 doubled that to 144 mbps.

If you have any tips on bumping this speed up, let me know.  Thanks

Hi  Foothill

My router is DIR-855 Xtreme N.. 144mbps thats the speed I got after the 6200 was installed, you need to change some settings...


1.download the lastest driver for the 6200 from Intel website

2. Go to the properties of the Intel 6200 adapter which can be found (Control Panel\Network and Internet\Network Connections)
right click on the Intel 6200 icon then properties; configure; advanced.

(see image below)

These are the settings I am using for the adapter which gives me 270-300mbps depending on where I am in the house

802.11n Channel Width for band 2.4 = Auto
802.11n Channel Width for band 5.2 = Auto
802.11n mode = Enabled
Ad Hoc QoS Mode = WMM Disabled
Fat Channel Intolerant = Disabled
Mixed Mode Protection = CTS-to-self Enabled
Roaming Aggressiveness = 4.Medium-High
Transmit Power = 5.Highest
Wireless Mode = 4.802.11b/g (you can change this to a/b/g depending on your have wireless a devices)

click ok and wait for the adapter to reset and you should be good, let me know how you got on

Day: 

Thanks a bunch.  The difference is amazing.  From the location I usually use this laptop I'm getting a high of 243mbps but the speed does change pretty frequently.

As I approach the router the speed increases.  When standing very close to the router I get 300 mbps, but even then the speed fluctuates. Being that close to the router sort of defeats the the advantage of having a laptop!!  Can you offer a suggestion as to what might be causing these speed changes?

Overall I'm pretty happy with the increase but would like to see the speed constant if not changing locations.

Thanks again for your help.

day187,

These are My Intel WiFi 5100 AGN Connectivity Settings, they're almost the same as you settings except The first one. I have the 802.1n channel width for band 2.4= 20mh ONLY.

I seem to get a hight download speed with my  Linksys WRT54GS. It keeps a steady 54Mbps and on auto it only goes to 48Mbps and fluctuates.

I will give that 20mhz a go see how i get on,,if you look at the picture in my post above I have my router set to

Auto 20/40mhz and i think that's work great but i will see what the 20mhz does for me...

thanks day

Hi mate no probs glad to help..

The speeds will decrease the further away you go from the router has you know, but it could be a number of things environment walls doors etc; router settings its hard to say..

I never had a netgear router so i dont know my way around them

but here is my router setting see picture below...

You could try playing with these settings in the adapter properties..

802.11n Channel Width for band 2.4 = 20mhz (try putting setting on 20mhz instead of the Auto)
Roaming Aggressiveness = 4.Medium-High (try different settings)
Transmit Power = 5.Highest (try different settings)

day

Channel 11 did not work for me only connected at 130mbps..will play with some channels and see if i get any improvement...thanks again day

Day

I've been trying different settings one at a time ever since my last post.

I can make the speeds decrease but I think your original settings are the sweet spot.

I can live with what I have now.

Hard to understand why Dell would sell a laptop with that DW1501 wifi card  in it.
