• What Hardware version is your router? Look at sticker under the router case.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.

Possible that the CAT5 cables are Mfrd differently. CAT6 is preferred:

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

I have the 835 however I haven't tested it with CAT5 cables. My main cables are CAT6.

Hi,

The Hardware Version is A1 and the firmware version is 1.04.

Possible that the CAT5 cables are Mfrd differently. CAT6 is preferred:

If this was an issue right out of the box I might agree with you, but since everything had been operating correctly for at least 2 years and now all of a sudden this has started happening, I really don't believe the issues to be the cables.  To rule it out I've even tried multiple cables, that I use at work and know that they function properly. 

I'm not sure if I said this in my previous post, but I did not change any settings at all since I initial set up the router.  Could a setting have set itself?

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

I swapped out the cable between the Modem and Router and the results were the same.

Thanks,
Seb

Theres nothing in the UI that can be changed to effect what type of cable can be used.

Only thing I can think of is something changed. Possible internal failure maybe happening.

Where is the router placed?
We have seen some heat issues with this model router and the DAP-1533 which is it's companion AP.
I recommend using a laptop fan under these units.

What was the symtom that lead you to change out the CAT5 for CAT6?

[stantalo]

The router is in my basement on a shelf in a cool dry area, with the rest of my networking hardware.  I added the CAT6 cable in December when I upgraded my NAS.

[FurryNutz]

So it was working well before adding the NAS and CAT6?

What made you use CAT5 after adding the NAS and CAT6?

[stantalo]

It was working well before and after adding the NAS and CAT6.  It worked well for over 2 months. 

I made the change because my previous NAS didn't support CAT5 and my new one did.

[FurryNutz]

Oh...well not sure if changing the NAS out has been the cause or not. I presume that upgrading all to CAT6 is best. I tend not to run mixed CAT cables if I can help it.

If your not experiencing any major problems, I presume you'll be ok.

[stantalo]

Ok, so now this gets a little stranger...  I previously tested each of the ports with the CAT6 cable that was connected to the NAS and confirmed that each of the four ports are working correctly because I was able to access the NAS while it was plugged into either port.  Well this appears to only be true when the NAS is connected.  I just tried a hard wired connection to my laptop using the very same CAT6 cable that the NAS is using and I am unable to see the network. 

Thoughts?

[FurryNutz]

How do you mean it can't see the network? Is the LT getting a IP address?

What Mfr and model # is the NAS?
Is the NAS and LT set up for reserved IP addresses?
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.

I recommend using a static IP address ON the NAS thats outside of the routers main DHCP IP address pool. I have my DNS-345 set up as .0.34.
FYI:
DHCP/Dynamic Addressing/IP Reservation/Static IP FAQ

[stantalo]

I'm not sure if it's getting an IP address, but I can't ping the router...

The NAS is a ZyXEL NSA325 v2, and no it is not set up for a reserved IP address, neither is the laptop.

[FurryNutz]

I recommend setting up a reserved IP address for the LT ON the router.

Set a Static IP address ON the NAS for .0.25 or .0.32

[stantalo]

Ok, so I've set both the NAS and the LT to have static IPs.  I've done some further testing...

I tried to ping a.root-servers.net from my NAS and it failed.  I also tried checking for updated firmware and that connection timed out...  Which leads me to believe that it can not access the internet.  There are the IP settings on the NAS:
IP Address:  192.168.0.100
IP Subnet Mask:  255.255.255.0
Default Gateway: 192.168.0.1
Primary DNS Server: 192.168.0.1

Here is what is on the Router:
IP Address :  192.168.0.1 
Subnet Mask :  255.255.255.0 

This all looks right. Am I correct?

Is there something else I should look for?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?
• Turn off TrueGigaBit Routing under Setup/Internet/Manual for those routers that have this feature for testing.
• Enable or Disable Use Unicasting (compatibility for some ISP DHCP Servers) and test under Setup/Internet/Manual. Disable may help with speed performance on higher speed ISP services.
• Turn on or off DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench and input new DNS addresses under Setup/Internet/Manual.

Is DNS relay enabled on the router? Disable it and test. You'll need to reboot the router and all devices.

It was on, and I've since disabled it

With all the changes above I am still having the same issue.  How is it that I can browse the web with my laptop that is connected wirelessly, but not with something that is hard wired?

[FurryNutz]

And this happens with all wired connections?
Do you have access to the routers UI on wired connections?
