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.
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.
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

. 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:

Here is another result:
http://www.speedtest.net/my-result/3049633544But 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.
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.
