Wow and banned you from the forums. LOL. Ya, Cisco has some good stuff, however when they don't recognize that they have made a mistake and don't realize it, eh, time to find another place to hang. Glad your around man. Thanks for all the help here. Trying to keep things running smooth there. All help is appreciated. Promise not to ban you here. hehe.

FurryNutz, getting ready to do some testing on both 2.01EU, and the latest 2.05EUB09 firmware once the kids are in bed. I'm going to deactivate WLAN for the testing period, but I was wonder which other feature(s) I should deactivate to make the router perform. I'm guessing that QOS should be off, but what about SPI? Any other features I should deactivate?

[FurryNutz]

I would test right after the last factory defaults. It's ok to turn off the wireless radios. It should run well with out having to turn off anything else like if you just pulled out of the box. Test as is.  After you get initial testing in, you can turn of things like QoS, WISH, Protected WiFi, SPI and do some follow on testing. Keep us posted. Hope the 2.01 works better.

[TrondS]

I've already downgraded to 2.01EU and my laptop is back to 130 Mbps. If this is because of a factory reset, or firmware remains to see. I'll get back to you later tonight with some results.

[Patrick533]

Qos always seems to be a problem for me, at least manually set it to the speed you have. Mine always seems to default to 1Mbps. When I manually set it to the speed I have, it works as advertised.

[FurryNutz]

Ya I have noticed that sometimes QoS and automatic uplink speeds works well either manual or auto. I see some situations where that uplink speeds are higher than 5Mb, it's best to leave it set for Auto. I have a 2Mb uplink and have mine set for manual 4096 just to give the router a bit of over head even though the link is pretty much capped at 2Mb, I see a tad bit over 2 and thats about it.

Keep us posted TrondS. Exercise that FW.

[TrondS]

Okay, so here are the results of my testing:

Test performed on a HP ProBook 4520s running Windows 7 Professional 64-bit. I used a wired Gigabit connection from the laptop. Test was performed in Firefox 8.0.1 with Flash 11.1.102.55. Windows 7 firewall activated, Microsoft Security Essentials active. I did no change in laptop position, wiring, or configuration on the test machine during the testing.

All configurations tested 3 times, and I'm giving the average of the three performed tests:

Test 1 was performed directly with the cable modem and gave me; 23 ms ping, 70,52 Mb/s DL, 9,79 Mb/s UL
Test 2 was performed with DIR-825/2.01EU firmware and gave me; 20 ms ping, 32,06 Mb/s DL, 7,82 Mb/s UL
Test 3 was performed with DIR-825/2.05EUB09 firmware and gave me; 23 ms ping, 68,92 Mb/s DL, 9,80 Mb/s UL

After tests were performed I also tested the WLAN speed towards the built in WLAN card with latest drivers installed:

Test 2 gave me 135 Mb/s link towards DIR-825/2.01EU
Test 3 gave me 65 Mb/s link towards DIR-825/2.05EUB09

So, it boils down to running 2.01EU and getting 130 Mb/s WLAN, or 2.05EUB09 and getting 70 Mb/s cable.

For my WLAN settings I have only 2.4GHz activated, Mixed 802.11n and 802.11g, locked on channel 11, auto 20/40, and visible, security mode WPA-Personal and WPA2 Only with AES cipher. The 2.4GHz band is on high with WMM and Short GI enabled.

Not sure what else I can do to "force" the WLAN client to connect at 130 Mb/s?

[FurryNutz]

Nice results man.
What happens if you disable Short GI for WLAN?
Can you now test with QoS OFF, make sure ALL options, even grayed ones are unchecked?
I would test again with out any windows security SW running as well. Just to be sure thats not interfering.

Sounds like the Beta FW might be your best bet. I'm curious if you would see the same issues if you connected a different type/model wireless adapter to the HP Laptop.

I think the beta FW would be good, if we can narrow down whats causing the wireless to not connect at 130.

[TrondS]

I disabled Short GI (even though I don't know what that is), and I turned the firewall off, together with the anti virus, but the link is still stuck on 65 Mbps. The Lenovo has a Broadcom WLAN adapter, and that connects at 130 Mbps just 3 feet away.

I'm starting to think that 2.05EUB09 isn't 100% compatible with the Ralink RT3090BC4 WLAN adapter located in my HP ProBook. Maybe any officials from D-Link is scanning the forums to pick up this, and can work on a fix in the next beta?

For now I'm willing to run on 65 Mbps WLAN, as long as my cable speed is 98% of what I'm paying for. My only concern is that it seems like the router is choking once I start pushing the router on download. I'm exploring the possibilities of swapping the WLAN card with a Intel N 6300 WLAN module, but this has 3 antennas, and my laptop only has 2, so I'm a bit concerned how that's going to work.

[FurryNutz]

Ya I think theres a possible incompatibility issue here.  IT would be a good test if you can find say a USB WiFi adapter that can do 130 or 300Mbs and see if they will connect.

I'll pass this along to my contact at DLink and see if they can review this. I can't promise anything. If they are doing some betas then this is good info for them.

Do some testing with downloading too and see how it goes. With and with out PC security, wired vs wireless.

[jmac]

I am having the same problem.

D-Link DIR-825 firmware 2.02NA
Thomson TM475

When I eliminate the router, I get 30MB/s download.  With the router in between, I get 3Mb/s download.  The upload is 1MB/s in both case which is the rated speed for my service.

I have switched the cables to Cat6, but no joy.  I switched QoS off and tried Auto versus 1000Mb/s.

[TrondS]

jmac, did you try to set the interface to 100? that was the only thing that helped me.

[FurryNutz]

Wonder if these Thompson modems could have some incompatibility with these routers. 

Jmac:
What ISP Service do you have? Cable or DSL?


Some things to try:
Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find these under Status/Device Info/Wan section.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

I've got a 825 that had 2.02NA and never saw this issue. However my modems were SB 6120 and now SB 6121 cable modems

[jmac]

> What ISP Service do you have? Cable or DSL?

Cable

> Some things to try:

Tried all of these things.  No luck except that setting the firewall to endpoint independent provides a slight improvement.

When I change the speed setting to 100Mb/s the download speed went up to 15Mbps.  With it set to anything else the speed is 3Mbps.  With the DIR-825 removed altogether, the speed is 30Mbps (at the service level for my cable).

I used two different host computers: a MacBookPro and a machine running Linux with an RTL8111/8168B.  No difference in any test.  So it's not the host.

I assume that setting the speed to 100Mbps limits my internal LAN to 100Mbps even though all my devices have Gigabit ethernet.

Thanks to TrondS and FurryNutz for the help.

[TrondS]

I don't believe that setting it to 100 will limit your LAN, that's for the WAN setting. At least my two wired clients show up with 1 Gbps connection when i hover over their icon.
