That doesn't help everyone but by support I'm guessing you mean phone support where they tell you to click here or there.
I can't dive in here but the manuals are there still. Share the exact version of the 615 so I can read the manual for your model.
Hi, recently switched to windows 10. Had issues with my internet port. I can now only receive wireless. In an attempt to get our computers on line again I think I created an unsecured link to the wireless. I tried to figure out how to put a password on it but there doesn't seem to be any help with doing this. The router is no longer supported by dlink. I found out how to do a reset (on this forum) and I did that but the open wireless connection is still there. Beginning to think it might be someone elses connection. I am in a 6 unit apartment building. I contacted my internet service provider to see if they had any suggestions but they don't. I would sleep better knowing that all my connection were secure. So long story short....how can I see what connections are mine and if they are how do I change one from open to secure ???? Im not very tek savvy so I really need some basic help .
