These couple last 2 days ago, i've been experiencing a really high ping, it's higher than usual.
No, it's not my ISP( i tried pinging my isp)
No, it's not my isp throttling my connection(tested my internet speed)
I used to get 170ish ping(because it's an US server);
Now it's 350ish ms, I have no idea what's going on, yes, I have wired.
and please, the person who is going to reply to this, just don't really say complicated stuff.

I'm extremely sorry, but I really didn't have any clue about what did you say.
Not everybody is as in networking as you.

Link>Welcome!

Please provide feed back as best as you can to the following:

• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?
• Are you wired or wireless connected to the router?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?
• Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
• What ISP Modem service link speeds UP and Down do you have?
• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values

1 : 1.02
2 : Finland
3 : Wired(i have already said that in the original post :O)

-------------------------
Welho (I heard that they have fiber cables)
(can't really get the name of the modem, i don't know what's the name of that modem nor the model name)
Dynamic
16 download speed, and 1.00 upload
it's gigabyte wired cable, to the router
1500

So if you test with out the router online with the PC you get good pings and when the router is online pings go up?

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. 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. I recommend having the ISP service physically check the lines going from the out side 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.

PC 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 LAN PC while testing.
• Disable any downloading client software managers, i.e. Torrents or similar.

Check your PC for many malware using MalWareBytes to scan...
Close ALL background running applications on test PC.
Turn OFF all wireless devcies while testing.
Disable the WiFi radios on the router while testing with a wired PC.

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy

• Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or AC on 5Ghz?
• 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. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
• 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.
• What wireless devices do you have connected?
• Ensure any devices with WiFi adapter drivers are updated.
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
• Any other WiFi routers in the area that maybe causing interferences? Link> Use InSSIDer to find out. How many? Use v3, its free.
• If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.

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."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

I'll check all of these stuff, I'll be back later and give you an response about this.

[Arugal102]

I've tried restarting the modem, disconnecting all the devices that are connected to the internet, then I tried to connect my PC to the internet, it somehow worked, I got my ping back(170)
The modem was just pretty much throttling at it's edge, I need to get a new one by the way, anyway thanks for the help and spending your time helping me.
Have a nice day.

Glad you found the problem. I have the 880L as well. Good router.

Enjoy.
