In the settings of the browsers, look for something called Page Styles. Disable or try Author mode.

nothing really pops out that works...I found Style Editor in Firefox but no option to turn Styles off. Like you said, it most likely doesn't work anyway.

Re: Very slow speeds on IPv6
« Reply #19 on: April 16, 2014, 09:07:45 AM »

so, this is how my Cable Modem is set up for IPv6:
The Gateway Address ((Link-Local) is populated
The Gateway Address(Global) is populated
The IPv6 Address Assignment is set to Stateless (Autoconfig)
And FromISP(Autoconfig) is also checked.

So do I select StaticIP or Stateless or Link-Local on the IPv6 Connection Type?

I'd recommend that you contact the ISP to make sure the modem is completely set up and enabled for IPv6 and that it can hand it off to any devices..Not sure if Link Local needs to be used on both the ISP Modem and or the DAP...I would set Stateless on the DAP and test. Try them all and  see what you find out after ensuring the ISP Modem is correctly set up though...

Let us know if you can change the 1525 to AP mode, shut off any Wifi on the ISP modem and test IPv6 on the 1525 and what the results are...

that isn't how I want to use this hardware so am not interested in testing the AP out. if it doesn't work as advertised as a Bridge and provide IPv6 support I'll need to return it.

Just thought it would be a good test. Thats ok.

I'd contact D-Link support and ask about Bridge mode and IPv6 operation and if it's supported in Bridge mode. I would think it is and should be working.

Ask for level 2 or higher support regarding this...

Keep us posted...

I spent some time yesterday with tech support but was no help. I got an email as well from someone else at D-Link with some bizarre suggestion about turning the cable modem into a Bridge which again isn't how I want my network setup so won't be trying that. I also explained in the email that it's been tested that the cable modem is properly configured and when a device is hard wired, to it, the IPv6 is very close in terms of speed throughput to the IPv4 so the issue is at the DAP-1525. They seem unable to get their device properly configured.

I've asked for an update from my contact. They are trying to find out if it's supported in bridge more. It's only mentioned in AP mode in the UM. Please be patient.

Do you have a case # that you got when you called D-Link?

This is under review now and I'll like to get my contact a case # for reference please.

Please PM me the info, no need to post here.

Thank you.

Hi,

Quote
so, this is how my Cable Modem is set up for IPv6:
The Gateway Address ((Link-Local) is populated
The Gateway Address(Global) is populated
The IPv6 Address Assignment is set to Stateless (Autoconfig)
And FromISP(Autoconfig) is also checked.

It's hard to judge your cable modem's IPv6 settings without more insight into the technical details of this device, which indeed operates as a router with an integrated cable modem. So if you tell us about IPv6 address assignments and gateways it is not clear if this refers to the WAN (cable) or LAN side of your router. But on the other hand it doesn't matter, because you seem to have perfect IPv6 access with any device that is directly connected to your router.

So do I select StaticIP or Stateless or Link-Local on the IPv6 Connection Type?

This depends on what you want to do with your DAP-1525. Whatever you select here should be irrelevant for the basic operation of this device, namely just stupidly bridging IPv4 or IPv6 packets from wired to wireless and vice versa.

This configuration item only refers to the IPv6 communication capabilities of the DAP-1525 itself (as a source or sink of IPv6 packets independent of its mere IPv6 passthrough bridging function for IPv6 packets not destined for or sent from itself):

  • If you select Link-local Only (the default) the DAP-1525 is only able to talk to local devices via IPv6, e.g. you can reach the web interface from any local device within your LAN/WLAN via DAP-1525's link-local address (fe80:...), but DAP-1525 is not able to talk to the IPv6 Internet via IPv6
  • If you want your DAP-1525 to be able to talk to the IPv6 Internet it needs a global IPv6 address. You can do this manually (by selecting Static IPv6) or automatically (by selecting Autoconfiguration (Stateless/DHCPv6)) which is recommended.

But all of that has nothing to do with your problem: Obviously your DAP-1525 has a problem with bridging IPv6 packets WLAN to LAN and/or vice versa. You can check if this is true by connecting one PC (call it PC1) directly to your router (cable modem) and another PC (call it PC2) to your DAP-1525. You could then measure network performance between PC1 and PC2 via IPv6 versus IPv4 (e.g. copying huge files between them from local disk to a remote network share and measuring the time it takes, and then calculating the network velocity [file size]/[time] or even more simple by looking at the network tab of the Windows Task Manager). You should see the same discrepancy between local IPv4 and IPv6 network velocity as you observed with IPv4 and IPv6 communication to the Internet, this way clearly having demonstrated that the DAP-1525 is responsible for this.
