The Graveyard - Products No Longer Supported => Routers / COVR => DIR-645 => Topic started by: femrilu on October 21, 2013, 09:41:12 AM

Hello,
I've been unsing my DIR 645 for quite a while now, tho I was never satisfied with the WLAN performance it was enough to keep up my 19 MS in games most of the time.
Now a new problem has arrived.
After installing Windows 8 and 8.1 the internet speed drastically slowed down. I did alot of measurements to get back my speed.
One of them was setting my router to b/g or g only instead of g/n and believe me or not, I never had this much speed in my WLAN connection:
20Mbits download with 50%connection. I was so happy.
But shortly afterwards I noticed that my ping in games (primary League of Legends) went up to 100+ and would stay there for a long time.
Doing speedtest with speedtest.net and unitymedia speedtest resulted in the same ping of 140~.
The laggs would disappear after a time, but they come back rahter quick and since I also enjoy streaming its really hard on me, while having 20ms w/o stream and 100-600 while streaming was just too much.
I also tried to setup my laptop right next to the router, even now the speed would be slow (when it already slowed down) and my download would be 0,80mbits.
Anyone knows what might be causing these random problems? Or is the WLAN of my router malfunctioning?

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.
- Turn off ALL QoS (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS (http://en.wikipedia.org/wiki/Quality_of_service) or Gamefuel.
- Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
- Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
- Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0)
- Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
- Ensure devices are set to auto obtain an IP address.
- If IPv6 (http://en.wikipedia.org/wiki/Ipv6) is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
- Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI (http://en.wikipedia.org/wiki/SPI) to test.

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
6" minimum safe distance between devices.
If you installed Windows 8 and only noticed this afterwards, I would presume that Windows 8 could be a culprit as well. Ensure any wireless adapter or wired LAN cable adapters are up to date on drivers if any are used.
Does this happen on a wired LAN cable connection as well?

Hello,
I am using D-Link DIR 645
I am using Version 1.01
I am in Germany.
No factory reset since the problems started.
My ISP has Cable. Information on the Modem will be edited.
My Modem should be supporting 32 mbits down and 2,1 mbits up.
-QoS is disabled, Traffic Shaping - no idea where that option is. sorry.
-Advenced DNS is turned off now, will see how it works.
-Unicasting is enabled now, will see how it works.
-DNS Relay, since the note says that its better to stay with the IPs given from my ISP, I will save this option for later.
DHCP reserved UP addresses are saved, will she how it works.
-Dvices are already set to auto obtain IP address.
-IPv6 is set to link-local only
-Firewall set to Endpoint Independent for TCP and UDP. SPI is enabled now, will see how it works.
-uPnP is enabled, Multi Cast streaming is disabled for now, will see how it works.
-Sorry, no idea where WISH and WPS are.
-WAN set to 1000Mb manually, will see how it works. EDIT: Connecting to the internet after setting it on 1000Mb failed.
-Time was already set to ntp1.dlink.com
-Will check if it's a Cat 6 cable later.
-SSID was changed already.
-as stated I am using g only for now, since g/n seemed to slow everything down, even though I have a Bigfoot Killer Network N -1202 Card
-DIR 645 is supposed to support 2.4Ghz and 5 Ghz, I cannot find any options for 5Ghz in the menu tho.
Singled mode N was horribly slow aswell and blocked out every other device in my home.
-Choosing a channel is hard at the moment. I am living right in the middle of our small town, so I cannot possibly have 3 channels distance from the other routers
-I am using WPA2-AES at the moment. After researching about Windows 8 I found out that TKIP should make my speed faster (seems to be an issue with Windows 8). So did I and it indeed was faster.
But after setting my router to g only there was not any difference anymore.
- Indeed we have 2 Cordless phones about 2 meters away and 1 meter below the router.
- There are 4 other routers at the moment, sometimes we have up to 6
- Disabled Short GI, will see how it works.
Only have the Windows Firewall on and the Microsoft Defender.
We have no wired LAN cable connection in the house, next time I encounter this problem I will try connecting my notebook via LAN Cable.
The current speedtest:
http://www.speedtest.net/my-result/3049625469 (http://www.speedtest.net/my-result/3049625469) note: the results vary alot :x
Here is another result:http://www.speedtest.net/my-result/3049633544 (http://www.speedtest.net/my-result/3049633544)
But as I said the problems randomly occur, so I will keep these settings and see if the drops still happen.
Moving the router away is problematic.
The Modem is connected to the Router via a 50m Lan cable, which was cheap so I am not sure if it is Cat 6.
Windows 8 is not neccessary the problem, since the other notebook with Windows 7 also had slow speed when I tested (next to the router).
EDIT: I just realized that my laggs while streaming might be due to my Upload since it's way weaker than before o .o.

Hello,
I am using D-Link DIR 645
I am using Version 1.01 < there is newer version available however lets see if you really need to update first.

Are these phones any where near 2.4Ghz frequency?

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.

Thanks, I will try stuff you mentioned out this weekend!
-
;)
-
Factory reset done.
Mixed g/n slowed the internet down as I mentioned g-only was the best till now
will be editing more
-
Keep us posted. Try w short GI and HT20/40 coexistence off aswell.
Lets us know your surroundings using InSSIDer app.

Funny thing: All other routers around us have been shut down it seems, my dlink is the only one left right now (10pm in germany)
And right now, my internet is slower. Downloading inSSider with only 30kb/s. Speedtests showing 50ms ping and 3mbit down / 1.8mbit up
EDIT:
Ok nevermind, it was prolly an update bug, but now InSSIder shows me 7 other routers
http://puu.sh/50giY.png
EDIT2:
Okay, seems like my network card is bugging? Because now, only my own connection is showed..
EDIT3:
http://puu.sh/50gX5.png
I don't have HT20/40 options...?
EDIT4:
Set my WLAN settings to mixed n/g for now.
http://puu.sh/50hLP.png
EDIT5:
Going to get a Lan-Cable and test my speed router -> notebook and modem->notebook
EDIT6:
router->notebook: same results as with wlan. 30ms 3-5mbits down and 2mbits up
modem->notebook: this surprised me.... 30ms 1-5mbits down and 2mbits up
I will try the find faster DNS option
EDIT7:
Changed my DNS:
20mbits down
2mbits up
2ndtest:
24mbits down
2mbits up
slighty better than before.
If more problems arise I prolly need to contact my ISP.
Since the results are very similar, me lagging while streaming must be windows 8 and incompatilbe drivers (using the newest driver for windows 8 already..)
EDIT8:
Back upstairs.. speed dropped lol.. I will go to sleep for now...

Maybe someone can review your router settings with you using Link> teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.
-
I wouldn't mind,
if any1 wants to help me, feel free to pm !
-
Send me a PM with the Teamviewer ID and PW and a time frame of availability. Please be wired to the router with 1 LAN PC.
Will see if we can help you out...
-
My access to the router would be at late nighttime in germany.
Are you from america?
-
I am, MST time zone here...I presume late night there would be early morning here? ???
-
If we do it 11pm my time, then -7hours its 4pm your time.
-
Any chance to bump that back to 2-3pm my time?
-
Would be rather hard for me, since the router is downstairs, where we have guests throughout the day (it's a little restaurant).
-
Ok, well 4pm is around the time framed I'm headed home. I could try to be online sometime after that...
-
doesnt have to be 4pm for you.
6pm is 1 am for me. If it's on thursday or friday then it's fine!
-
Lets try for Thurs for Friday. I'm celebrating my b-day here today and will be out with friends at dinner so this afternoon will be tied up... ;D
-
Sounds good!
-
Ready?
-
Internet works fine, but it is like before.
Random downtimes, everytime I experience such a lagg, I ping my router via cmd, and then I ping the google servers.
Today I lagged and pinged my router, and had pings between 40-1400 with timeouts.
Then when that was stable again, I pinged the google.de servers. And the ping there was stable at 30.
There might be a problem with the surroundings of my router or my router in generall, I am not sure since my internet was fine not so long ago.

Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
6" minimum safe distance between devices.
I would start by turning everything OFF. Test with only 1 device at a time. Find the time frames on when you seem to experience this lag and test with 1 device. PC or otherwise. Could be something on the LAN side causing this.
Do you have any close friends or family that you could test this router out at there place by chance? Would like to know if the problem follows.
-
I highly suspect it might be due to my LAN connection or the router.
As you have seen in our Teamviewer session, my speed varied alot, even when being connected via Lan!
I will see who I can ask to test it. Ty
-
Keep us posted.
-
Little sidenote:
We might move soon, or rather build a house. So I guess I can endure this for now and wait abit.
(unless my internet starts to srsly die hard xD)
-
Another question, I can't log into my router, there is no username given (I set a new PW)...
So I tried 'admin' as Admin, admin, ADMIN etc.
But I can't log in

Web Browser Configurations
What browser are you using?
Try Opera or FF? If IE 8, 9 or 10, set compatibility mode and test again.
Disable any security browser Add-ons like No Script and Ad-Block or configure them to allow All Pages when connected to the router.
Try turning off these features in Chrome:
Top right corner, little bars for options > Settings > Settings (on left) > Show advanced settings.
Uncheck these:
Use a web service to help resolve navigation errors
Use a prediction service to help complete searches and URLs typed in the address bar
Predict network actions to improve page load performance
Enable phishing and malware protection

Since the laggs became even more ******ed, I did another reset and now I see something suspicious:
(http://puu.sh/5lb8N.png)
this is the PC I am connected with to the router, the other one, which is standing right next to the router has 11g, but this one has 11b
(http://puu.sh/5lb9W.png)
My settings only allow 11g or 11n, tho...
-
maybe some interferences causing it to kick down to B mode or the router is reporting the connection incorrectly.
Can you move the router or PC farther away from each other to test? Say 10-15 feet and see?
Ensure your wireless drivers on the PC are up to day and that the properties of that wireless adapter are configured to allow for N modes. I've seen some drivers default to B mode only or G and not allowing N mode. Refer to the Mfr support site for information for your wireless adapter for that.
-
My Killer Networks Manager says this:
(http://puu.sh/5lfhW.png)
So it might be my router forcing my connection down to 11b?
-
What happens if you test with single mode G then single mode N?
-
single mode g: also 11b
single mode n: 11n with rather low Mbps for that standard.
I tried to setup my DIR-615, but I can't connect via LAN or WLAN, so I went back to the DIR645
-
Ok N-Only also results in b
-
Seems like something on tue router doesn't like your device or your device isn't working right
-
Any other way to see which one is causing the problems? I can't connect to my DIR 645 :/
-
Try setting channel width from 20 to auto 20/40mhz. Then turn off HT20/40 coexisitence under advanced/advanced wireless and use single mode N and test...
