DIR-601 slow internet
« on: April 21, 2011, 03:44:05 PM »

Alright, well I bought the DIR-601 and set it up a couple months ago, everything went smooth and was fast. Then a month latter we lost power and the internet was horribly slow. I just reset everything and speed was back. After than something happened and the internet was slow yet again. Was like that for a week but I ended up unplugging the router for 30 mins and it was fixed. Now last night it decides to take a dump on me again. I unplugged the router and left it for an hour and got nothing, reset the modem then the router and still nothing. It took me 3 mins just to load this page. I have comcast high speed internet and normally have about 20-25 mbps.

This has been constant and is driving me up a tree. Can some one tell me how to fix it?

Silly question, but you are on firmware 1.02?

Otherwise you might want to try dd-wrt on it.

Are you getting the same thing when directly connected to the ISP modem?
What ISP modem do you have?
Is the modem stand alone or built in router?
Check the logs on the router and see if there is anything around the time frame regarding a disconnection or a problem.
How are you connecting to the router? Wired or wireless?

I would first trouble shoot the issue before going to 3rd party FW.

I am on 1.02NA and have occasional slowness, some sites taking forever to load, then a resend may help. Or not.

Log is full of

Blocked incoming TCP Ack packet from 192.168.0.105:3590 to 68.41.69.102:18514 with unexpected sequence
Blocked incoming TCP Ack packet from 208.43.202.40:80 to 172.16.1.11:3636 with unexpected sequence

Chrome does not display router info correctly, slowness may just be on Chrome.

Thanks.

What ISP modem do you have?
Is the modem stand alone or built in router?
Is QoS enabled? Disable it?
Enable DNS relay if you have it.
Disable Advanced DNS Service if you have it.

Try using a different browser like Opera, FF, Flock

DSL modem is Netopia from Earthlink, stand alone.

Enable QoS engine is checked;what would disabling it do?

Not sure where DNS relay is found; same as dynamic DNS? I don't have a domain name.

Advanced DNS Service is disabled.

FF seems to work better.

Blocked incoming TCP Ack packets normal?

thanks.

I'm having a similar problem, but it is caused by the fact that when I connect direct with Cat5 to the router, the maximum speed allowed by the router is 10Mbs.  I can see this on my windows machine.  It tries to negotiate a normal 100 Mbs connection, but fails.

QoS is mainly for working with 2 or more devices that are online at the sometime and competing to get bandwidth. If you only have one device connected or only have one device online at a time, QoS is not needed.
If your router has DNS relay it would be under Setup/Network settings.
I would also ensure that Primary and 2ndary DNS IP addresses are being filled in under Setup/Internet/Manual.

Your DSL modem should be good then. Some DSL modems have a built in router that can cause some connection problems with adding another router online.

The Blocking messages are what can be seen and reported by the router and it's just telling you that it's doing it's job. Does come in handy sometimes when troubleshooting.

I do run several devices online at the same time so will keep QoS.

DNS relay is enabled.

Under Setup/Internet/Manual both DNS IPs are 0.0.0.0 and Use Unicasting is checked. Maybe this is a problem.

Under Windows TCP/IP properties Obtain DNS server address automatically is checked.
ipconfig /all :
 Dhcp Enabled. . . . . . . . . . . : Yes
 Autoconfiguration Enabled . . . . : Yes
 IP Address. . . . . . . . . . . . : 192.168.0.100
 Subnet Mask . . . . . . . . . . . : 255.255.255.0
 Default Gateway . . . . . . . . . : 192.168.0.1
 DHCP Server . . . . . . . . . . . : 192.168.0.1
 DNS Servers . . . . . . . . . . . : 192.168.0.1

Under Status/Device Info/WAN:
Primary DNS Server :      172.16.0.254
Secondary DNS Server :      0.0.0.0

The earthlink dsl modem lists
DNS Servers: 207.69.188.185, 207.69.188.186
I don't know if these are static so may not want to write them into the router?

thanks again.

need to put in the 172.16.0.254 address in the Setup/Internet/Manual section.
The device are showing correct values.

My Netopia dsl modem is resetting itself every few minutes with the DIR-601 connected: PPPoE light goes off with a click. Earthlink had me bypass the router and plug directly into the modem; so far it has not reset.

Is this a known problem with this router? Is there some router setting I should change?

thanks.

Hmm, not that I know of. Could be a compatibility issue between them. I wouldn't think so though.
Something in the configuration between the two would be and issue.

Are you setting up the 601 for DHCP or PPPoE connection to the ISP modem?

Also make sure the cabling between them is good too. The shorter cable the better.

On the DIR-601 I am using the Dynamic IP (DHCP ) setting since that is what I used on my previous router.

I think the modem resetting may be due to windy conditions here causing a very short power interruption.

I still have the slow loading problem, stopping and reloading the page most of the time fixes it. Maybe DNS issue?

One interesting thing I noticed with Chrome is when the website has a hard time loading the little waiting icon in the tab is gray and spinning counterclockwise; when the website is being found quickly the icon is blue and rotating clockwise.

Possible DNS issue. Are there any other DNS addresses that your ISP can provide you?
What happens if you try a different browser?
