I have been having this problem where I can't save anything on my DGL-4500 (the router reboots upon hitting save). I am using firmware 1.15 (non-beta from the website).
After much soul searching, I found an article that suggested enabling wireless to solve the problem (this was a different router a DIR655 I think) (of course this takes a hard reset of the router, since I can't save any settings after turning off wireless).
Nevertheless, there appears to be a problem with 1.15 on the DGL-4500, after wireless is shut off, no new settings can be saved. Might be worth looking into for the firmware writers.
hello, i have the same issue. (cant save. router turns off/on) however i have a way around this problem when it occurs. i will give step by step hope is helps..
I am usin firmware 1.15
1. go to 192.168.0.1 log in.
2. go to tools, system settings.
3. create a new (save configuration) if you have 1 with all ur setting skip this step.
4. under system settings click Restore all settings to the factory defaults
5. let router boot up. 3-5 mins at lest.
6. after boot up. 3-5 mins. then press the reset button on back of router. router will power cycle, release reset button.
7. after 3-5 mins log back in 192.168.0.1
8. go to System Settings an load configuration file. (done) maybe
i have 2 saved files 1. with wifi turn on. 2. with wifi turn off. since i cant turn off/on when i want.
after loading new file the router is behaving normal.. however sometimes i get (cant save reboot syndrome) i just reboot. load saved file and back to normal..
