WLAN spikes and downtimes
« 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?

Link>Welcome!

  • What Hardware version is your router? Look at sticker under router.
  • Link>What Firmware version is currently loaded? Found on the routers web page under status.
  • What region are you located?
  • Has a Factory Reset been performed?


Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?
  • What ISP Modem service link speeds UP and Down do you have?
  • Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
  • For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

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 or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS 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
  • 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 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 to test.
  • Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
  • Turn off WISH, and WPS under Advanced.
  • WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
  • Set current Time Zone, Date and Time. Use an NTP Server feature. Tools/Time.
  • Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion
  • Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
  • What wireless modes are you using?
  • 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
  • Channel Width set for Auto 20/40Mhz or try 20Mhz only.
  • Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
  • What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
  • Any cordless house phones?
  • Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
  • If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, disable HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
  • Enable WMM Enable Under Advanced/Advanced Wireless.
  • Try setting Medium or Low power output settings and test again Under Advanced/Advanced Wireless.

3rd Party Security Software Configurations
  • Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
  • Turn off all devices accept for one wired PC while testing.


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 note: the results vary alot :x
Here is another result: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.
I am in Germany.
No factory reset since the problems started. Lets do a clean factory reset from the UI under Tools/System and set up from scratch.

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. Found under Advanced/QoS

-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.

-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. IF you have them, they will be found under Advanced.

-WAN set to 1000Mb manually, will see how it works. EDIT: Connecting to the internet after setting it on 1000Mb failed. Leave on Auto if your ISP modem doesn't support 1000Mb WAN connections.

-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. This router only supports 2.4Ghz WiFI.

Singled mode N was horribly slow aswell and blocked out every other device in my home. Set for Mixed G and N.

-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
You maybe encountering WiFi congestion here.

-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.
Are these phones any where near 2.4Ghz frequency?

- 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:

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.

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...

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...
