I've been using the dir655 for about a year now and never had a problem with it until recently. Now if I'm one room away from the router the rate and single strength drop to next to nothing. If I'm in the same room they both are ok strength, although not as high as I would like.

I installed firmware 1.31 to see if that would help but it did not. I'm a bit of a novice and haven't been able to find anything software/hardware related that would do this.

Do you live in a populated area?  Has someone else moved in near by and maybe they have a router too?

[uconnray]

Apartment building. Not sure about the moving though I don't think so.

I tried everything I could from reading forum posts etc...to increase the signal but I'm pulling 1 Mbps about 20 ft away and nearly line-of-sight.

Hi,

I second the vote for (new) neighbors causing your issues....

You may have to manually set the wireless channel, if in fact you have a neighbor now using another wireless router (or access point).  Many units default to channel 6....

It is not uncommon for apartment buildings to become flooded with WiFi signals, and with a limited number of channels, eventually there will be problems.

This may not even be it, but atleast we could rule it out.

try download that wifi inspector. 

also post your wireless settings (the ones on the advanced page too).

Then post the results you get from wifi inspector.

WAN Port Speeds: Auto 10/100/1000Mbps


In Network and Sharing Center, my connection speed is listed as 1Mbps.
In D-Link wireless utility, my connection speed listed between 1 and 70 mbps (usually below 10 though), signal % between 5 and 20.

I did a speed test with Wi-Fi Inspector and it came back with a download speed of 327 kbps. It also indicated that no wireless network in range was using channel 9 or 5, though there were a lot of other networks (only 1 other draft n).

No idea what to do about it. Do I need to get one of the D-Link N Extreme adapters for my laptop to boost performance?

ALSO -The Xirrus utility indicated that my transmit and receive rates were both 300 mbps. I'm getting very conflicting information based on what Vista is telling me and what the utility is telling me. But I know the connection is moving SLOW.

Wireless signals overlap.

So just because nothing is on 5/9 doesn't mean its the best channel.  Post the output of the scan.
Have you tried turning off "Extra Wireless Protection"? 

Maybe someone else has some better ideas.

[uconnray]

What scan do you want me to post the results of?

I just counted 20 wireless networks (not including mine) that the Xirrus utility is picking up, 7 of which have fairly strong signals....bummer.

Well, You said you were using the auto channel feature, and I can't comment on anyone elses luck with it, but I always had issues with it.

I was asking for you to post what other channels were being used.  If there are a lot of channels being used, it might be worth turning "Auto" to "20hz" in the channel width setting.  Then we can find you a decent channel to sit on.

[uconnray]

I left it on auto channel scan and changed 20/40 best to just 20hz. Still no dice....

The other channels being used are: 14 networks using channel 6, 8 networks using channel 11, 2 7s, 1 network using 10, 1 using 3, 1 using 2.

My router switched to channel 4 this morning and still really slow (1 Mbps).

[Demonized]

Go for channel 1. that will give you the least overlap and 'competition'.

The report '300 mbps' is not the actual transmitting speed. Most of the small utilities will give that false overview. You Vista network connection 'status' will give you the real connection speed.

[uconnray]

I relocated the router into my living room and sat 10 feet away from it and still am only getting 1 Mbps.

I changed to channel 1, disconnected, and reconnected, and the Vista connection speed briefly read 130 Mbps but then immediately dropped to 1 Mbps.

[poopdawg27]

hey what's your MTU at? 1500? try bumping it down to like 1470 this may help alleviate the issue.

[Demonized]

Either the router is broke or you client PC is not configured right. Try connecting without any security features enabled.
