I need help I updated the firmware of my wifi wr829n to the latest and it keeps saying that it is connected to the internet but there is no internet, the internet drops out all the time and my provider does not recognize that I am without internet. 

I think the problem is in the recent firmware I put. I unfortunately didn't make a backup so it's difficult to restore to a previous one. I try to downgrade but it fails and there it says that if it fails try to lower the clients. 2. If the update fails, it may be caused by not having enough space for the new firmware. Disconnect other clients or reduce bandwidth usage before trying again. how do you do that? I looked on youtube one that chose the firmware that would do the factory reset.
