Disable Port Scan and DoS Protection Misleading
Having noticed a slowdown in my internet and frequent lag, I checked my logs only to discover I'm getting DDoS attacks nearly every 15 minutes! They IPs are from all over the world. My first instinct...
Two months and no solution?? I am just confused by one issue here. Why is the 'Default' a checked box/enabled "disabled port scan and dos protection? Even the help pop-up on the same router page states it should only be disabled on 'special circumstance'. Thus I have to uncheck the box in order to enable the protection. But, and it's a big but, I do get the same dos attacks on an apple ipad every few minutes. My PC gets them also but it is the Router's DNS (75.75.75.75) attacking the IP/Mask. (??) This does seem to stop when I leave the box checked, disabling scans and protection. Doesn't make sense.
Also, neither Comcast nor Net Gear say they can adjust my modem/router clock and thus one hour behind. I don't see any clock settings incl. DLSavings time.
A little help pls..

On the Orbi web interface, Advanced Tab->Administration->NTP Settings is where the users has a choice of which NTP server to use and whether to follow Daylight Saving Time.
Thanks for taking the time to reply. I do not have an ORBI. (when I hit reply here it asks which device I have (c6250/AC1600 C/M/R). It seems that does not show up. (?). I also looked on the MYNetGear page and Comcast page. I'll call comcast again (NG always wants more $$ to get support). Regards
One of the "Top Answers" on the C6250 page is about Daylight Saving Time:
This appears to indicate that the C6250 does not have an option for DST.
The user manual is over 150 pages. I did not see any mention of Daylight Saving Time (or even NTP servers!)

The Netgear forum on "Cable Modems and Routers" has topics that mention the 6250. Maybe someone on there can offer suggestions.

Good Luck!

When I do a "nslookup" on 75.75.75.75 it comes up as Comcast's DNS server. If Comcast is the ISP, then I would expect to get packets from 75.75.75.75 There is a way to check, on the Advanced Tab->Internet Setup, what does it show for DNS servers?
It has been a long time since I did a "factory reset" on my Orbi, but my memory is that the only box checked on the WAN Setup was the Disable IGMP Proxy.
