HP OfficeJet printer seems to cause DoS messages in C3700
I recently installed a new HP OfficeJet 6830 printer. It is connected to a desktop via USB and also is enabled for wireless communication. Whenenver I turn the printer ON or OFF, I see messages lik...
Update on my issue... I did a full uninstall/reinstall of the printer and the issue has not been resolved. I also had 3 calls with HP Support which did not yield any improvement.
At this point, I've checked Disable Port Scan and DoS Protection meaning I have disabled the "protection". The DoS messages are still being logged however the C3700 does not seem to lose its Internet connectivity. Previously I thought that even with the setting on I was still having connectivity issues but after trying again, it seems that the messages are still there but the connection is not affected.
Based on what I've read, for a home network, this "protection" seems to be of limited usefulness so I'm ok with setting it this way. Also, I really don't want to have to return the printer and this is the only option that I've come up with for now.
Hi I have a related problem with my new Netgear C6300BD-1TLAUS cable modem gateway and my HP OfficeJet 6500a+ printer.
My problem is that my computer loses connectivity with the printer after awhile. If I turn off the printer and turn it on again, all works fine the for a short time but then it stops working. When I look at the modem's system logs, I see these messages about a detected teardrop attack coming from my printer.
I have tried removing the printer and reinstalling the printer, but the software can't communicate with my printer.
I have turned off detectiono of DOS attacks but this hasn't helped.
I've found a workaround to my problem.
If I go into the modem's Wi-Fi Settings and set the security option to to WPA-PSK (TKIP) then restart my printer, I no longer have my problem. If I use WPA-PSK(TKIP) + WPA2-PSK (AES) then I have the problem. If I use WPA2+PSK(AES) then I have more problems.
