THANK YOU!!!!! I was beating my head against the wall with trying to figure out why I wasn't getting more than 400M throughput. MSS clamping was the culprit. I owe you a beer.
thanks man. just come cross this one, it helps me on the wifi side :) i am still having trouble with my USG pass through speed down at 65 mbps while my isp is 640mbps, i will try the method u indicated
@@cokish1 bro, turn off threat management does really helped lol, it basically allow my speed back up to 640 mbps, i am so happy now lol, for a home user, i guess i dont need threat managment, appreciated it, only question though in the controller mode, the isp speed test sometimes doesnt work, how did you make it work?
@@tonywang1766 Yea. Speed test works great on mine. Try updating USG to the latest version. If no go, sign for 'Early Access' program on your ubiquiti account and use beta firmware for your USG. (you can also edit config via SSH to redirect speedtest to a different site)
One question. By disabling DPI and Threat Management are you leaving your network exposed to attacks? I was under the impression that DPI and Threat Management serve as the firewall.
Good point. But you don't need to disable it on a Dream Machine or dream machine pro. Only if you find an old USG somewhere and need WAN speeds over 300mbps. I see it that way. With Unifi Threat Management you are restricting access to malicious IP Addresses, but you cannot do real threat management yet: A/V scanning, HTTP / HTTPS interception, email filtering, data loss (PII / PHI exfiltration) protection, integration with Network Access Protection / Network Access Control systems, and more. You need a different router for that. And it doesn't disable your firewall since your LAN doesn't have access from an external WAN address, unless you specify it in rules otherwise. So in that particular case a client with USG prefers speed over threat management and doesn't want to spend more hardware money. So it's on user not to click on weird links and ads in this case.
Turning off DPI and Threat Management isn't really helping speed things up. What is helping speed things up is moving the channel width to VHT80+. Its basic wireless radio theory. The wider the band the faster it runs however its not as stable as VHT40 or below. You may see clashing depending upon the environment, etc. Its dependent upon your unique setup, there is not a one size fits all setup. You also need to make sure you look at hard setting the channel itself to keep it from overlapping. There are a lot of good videos out there that going into detail on how to do the channel setups.
setting the widest channels is generally bad advice... the wider a channel, the more prone to interference it gets. as well as required transmit power (thus possible pissing off the neighbors if you are in a busy location and disrupt their wifi) www.reddit.com/r/Ubiquiti/comments/6kx9dg/help_understanding_channel_width/ is a good reference.
Channel bonding - Wider channels directly increase throughput. If you want more than 500 Mbps on your wireless device - that's the way to go. Default Unifi channel width is too narrow for higher speed. This was set in a standalone house with no neighbours around. You can set Transmission power on your Unifi AP as well, It's a different setting.
All you did was turn off your fire wall. Defeating the entire purpose of using this router. If your internet speed is faster than the DPI THROUGHPUT of this device you should be using the PRO version which is rack mountable but can sit normally as well. UDM-PRO allows all TRAFFIC with ALL firewall features on. The throughput speed of traffic is 3.5 gbps with all firewalls on. That 3X times faster than the fastest fiber internet in the United States. And the pro is only 300$. Pennies for a great firewall
It's not all what I did. And DPI is not the entire purpose of using router either. Correct, you don't need to do it on UDM-Pro or Dream Machine. It's for older USG device. You might need to disable mss clamping on DM to get 1Gbps though.
