D-Link Router weakens signal
« on: March 01, 2013, 02:17:09 PM »

Hi, my D-link router seems to weaken my signal. I plugged my modem into my computer and I got around 40Mbs. When I plug it into my router and then my PC I get around 9Mbs. What is causing this problem? I have tried so many things in the settings and I have yet to make the signal change.

Link>Welcome!
What Hardware version is your router? Look at sticker under router.
Link>What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?
Are you wired or wireless connected to the router?
How are you determining the speeds? Using a speeds testing site or local LAN to LAN xfer? It's not recommneded to speed test via Wireless as many variables on WiFi can effect accurate results.

Has a Factory Reset been performed?

What ISP Service do you have? Cable or DSL?
What ISP Modem make and model do you have?
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.

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.
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 uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules.
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.
 
Link>Wireless Installation Considerations
What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or mixed G and N on 2.4Ghz and single mode N on 5Ghz?
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.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?

Turn off WISH, and WPS under Advanced.
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
Enable WMM Enable Under Advanced/Advanced Wireless.

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.

Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

What Hardware version is your router? A1
What Firmware version is currently loaded? 1.3 (Just updated)
Are you wired or wireless connected to the router? I am currently wired
How are you determining the speeds? I'm using my ISP's speedtester
What region are you located? Norway

Has a Factory Reset been performed? I just set it up as normally right out of the box

What ISP Service do you have? Cable or DSL? I think it's DSL
What ISP Modem make and model do you have? Unsure what you mean by this.

Can the internet browser I set it up in affect it at all?

What ISP Modem make and model do you have? Unsure what you mean by this. Is there a separate modem that the 857 connect too? If so, what is the manufacturer and model of this ISP modem?

Can the internet browser I set it up in affect it at all? Possible, try different browsers and see, Opera, FF and IE. Be sure to disable any 3rd party security programs and turn off other devices while testing.
