Hi Guy,

I have noticed that my router is droping the internet speed. Speed returns to normal after rebooting the router, but it drops after 1-2 hrs. Upload speed if fine but download speed is very slow.

If I remove the router and access internet directly via modem, the speed is normal throught the day.

I ran below test on wired network.

After reboot:


After 20-30 min:


I did following, to fix the speed.

QoS on/off does not help.
Reserved static IP address on the router, for devices.
Turn off Advanced DNS Services.
Turn on DNS Relay under Setup/Networking.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

Nothing of the above helped it.
 
There has been not firewire update since 2010 for this hardware version.

I will appreciate if somebody can give some suggestions.

Thanks.

Welcome!

What region are you located?

What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

Some things to try:

Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.

Enable uPnP and Multi-cast Streaming under Advanced/Networking.

Wireless Installation Considerations
Ensure WiFi adapter drivers are up to date.
What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
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.
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI, WLAN Partition and Extra Wireless Protection if you have it. 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. Cat6 is recommended.
