Posted: Thu Dec 04, 2014 2:58 Post subject: can't disable spi
I installed on a wrt54gv6 the micro build 25527 and configured as a repeater bridge according to the instructions. Everything works OK, although I cannot disable the firewall->SPI button. I'm able to click on the "Disable" but I can't save it. I also tried with previous builds but I get the same results.
I don't know how important is that step for the functionality as a repeater, but it may be for other people.
This is also true for
DD-WRT v24-sp2 (01/20/15) micro - build 25974
(also on a WRT54G V6)
I can save/apply for any other settings on the page, as long as I leave SPI enabled. As soon as I disable SPI the Save and Apply buttons no longer trigger when clicked.
The Access Point setup instructions said to disable the SPI firewall. This worked for the old build, but not with the new build. [Clarification: I couldn't get the "disable SPI" setting to stick on build 33535. After the workaround below it does stick, and my device is now working as an access point]
Open your browser's DevTools. (The following instructions are Chrome.) Go the the Elements tab and search for “log_enable”.
Look for the log_enable instance in a large commented-out block below the idfilter div. Right-click on this large block and Edit as HTML. Remove the comment prefix (<!--) and suffix (-->). Click elsewhere to remove focus from the HTML tag being edited.
Close DevTools.
Some extra form controls will now appear. For me these controls didn't have any labels. Click on the rightmost unlabelled radio button (corresponding to log_enable in the disabled state). Then the four unlabelled drop-down controls will disappear.
You might have to re-click some of the checkboxes.
The "Save" button at the bottom of Firewall.asp should now work. The ARP Spoofing Protection checkbox, which I had unchecked prior to saving, got re-checked. But that didn't prevent me from following the rest of the rules at https://www.dd-wrt.com/wiki/index.php/Wireless_Access_Point to get my device working as an AP.
When the time comes to Apply Settings, do it from a page other than Firewall.asp.

you must have a solid reason to disable SPI as this is not recommended at all...
only on certain cases as a WAP, client/repeater/WDS
some ppl believe disabling SPI gives a better speed...
now there is a SFE option for that on the new builds...
in general those routers affected by slow performance are very old and must be replaced instead of disabling
an important features in order to provide better performance as they cannot provide it at all... _________________ Atheros

Looks like there's a JavaScript issue with Firewall.asp. [...] The submitcheck function wants to check the value of log_enable, but for micro builds the log_enable control is commented out.
Thanks @hurlybuehrle; I recall this when I setup my WRT54GSv6, though I just disabled SPI via CLI as a workaround.
Good news though... This was broken in 19597, and BS has now fixed it in 40365.
