Cannot access internet after adjusting bandwidth

[DarkCentauri777]

I have AT&TFiber 1GB up/down. I initially setup the Netduma, and everything seemed to work. However I was only getting 50mb up/down on Speedtest.net from my wired PC. I followed the guide (http://support.netduma.com/support/solutions/articles/16000022366-why-is-my-connection-speed-lower-) and now I cannot access the internet at all.

 

The LAN side is up but I cannot load any web pages. Please help ASAP.

Hi.

 

Welcome to the netduma forum!

 

 

 

do a factory reset, enable turbo and super turbo modes to obtain full bandwidth........make sure you enable cookies 1st after the reset.......you will not get full gigabit speeds as the netduma only handles speeds up to 800mbps.

Okay. As per the guide, I already had Turbo and Super Turbo enabled. The only thing I did not do is enable cookies. Deep packet inspection was also disabled. Before the Netduma, I would get 900/900 on speedtest.net.

 

I tried adjusting my bandwidth again from within the router. I cannot set it above 300/300, otherwise the connection becomes unstable. Should I still factory reset as you suggested or maybe just try enabling cookies?

 

UPDATE: I went ahead and performed a factory reset. Nothing changed. I cannot set my bandwidth above 300/300 without the connection becoming unusable. Speed tests are close to what I have set.

Well, hopefully 1 of the more technical guys on here will help you when they see this post. The 1st thing they will tell you to do is follow the guide. Remember to always make sure cookies is enabled from the get go, ipv6 in wan, lan and misc is also disabled. 

 

Please note that it is late night here in the UK so any netduma staff will not see this til tomorrow......... I am mod box who is a mod on here is from the states and I am sure he will have a solution for you......just please be patient.

Well hopefully they’ll see that I’ve already done so. I’m really liking the performance so far. Now to get it to its maximum potential.

Hi, welcome to the forum! The maximum speeds you can get through the Netduma is around 800mbps, though that's under lab settings so you'll likely manage around 500-600mbps in a household. What happens when the connection becomes unstable? Does the Wi-Fi start to drop out? What about wired devices? Is the Interface still accessible when this happens?

 

Just to clarify (and make it easier to see in summary) these are the settings we recommend for high speeds:

 

- Reactive Algorithm

- 100% anti-flood

- Disable IPv6 in WAN, LAN & misc

- Disable deep packet in misc

- Enable turbo mode

- Enable super turbo mode

- Ensure the ethernet cables you're using connecting the R1 to hub & R1 to PC are Cat5e+/can handle your speeds, and try switching Ethernet cables

- Do a wired speed test from a PC

 

Please ensure that these settings are applied and let us know the results of another speed test.

All of your suggested settings I have tried.  WiFi is disabled on the router as I have an Orbi that is an AP.  The LAN side still works normally.  The interface is still accessible.  Even the Internet Diagnosis page shows exceptional for everything.  However no web pages/services will load.  It seems that the Super Turbo mode is contributing to this somehow... very strange.

 

My setup is as follows:

 

AT&T ONT > Netgear gs108E > AT&T Modem > Netduma > Orbi (AP Mode)

 

The AT&T modem, ONT, and switch act as a pass through to the Netduma via VLAN on the switch.  Any settings via the AT&T modem are not used because of this; additionally there are no devices connected to the AT&T modem except to pass through to the Netduma on the WAN port.

 

The only devices physically connected to the netduma are my PC, Xbox One, and Orbi.  The rest are either on the gs108e or wifi.

 

I suppose I need to ask, is this the best way to setup the Netduma?  Or should I have the Netduma behind the Orbi?  If so, how do I go about doing that?

I can't see how Super Turbo Mode would be causing websites to not load properly, since all it is supposed to do is turn off Device Prioritisation. The theory is that such high speeds would not require Device Prio. Are you sure websites load when it is disabled, but don't load when it is enabled?

 

We always recommend having all devices connected to the Netduma to fully utilise Congestion Control. Honestly I think your setup is fine, though the devices connected to the GS108E should preferably be connected to the Netduma. The Orbi should be fine in AP mode unless you can see an advantage to having it the other way around.

Barring any other configuration or setting, then yes.  I have gradually tried increasing the bandwidth amount set on the congestion control page.  When prompted to auto update the router based on the bandwidth I say no.  If I do, once I try 500mb or above, I notice that Super Turbo Mode is then enabled, and no web pages will load.  When I manually disable it, things run fine but my speeds are relatively low.  I have attached screenshots for reference via this link:

One of the reasons I have the switch is because I need more than the 5 ports than the Netduma provides.

Do you see a WAN IP address in the Device Manager? And also, do you require PPPoE to use the Internet on your connection? If you do, enter those details in WAN settings on the Netduma. Factory reset the Netduma, and then manually set it up for your speeds (enter your bandwidth, reactive algorithm, 100/100 anti-flood, enable turbo mode, Super turbo mode, cookies, disable IPv6 in LAN, WAN and Misc, disable Deep Packet Processing)

 

Then, try these steps:

 

Unplug modem and Netduma.

Wait 30 seconds.

Connect power to Modem.

Wait 30 seconds.

Connect power to Netduma.

Wait 30 seconds.

Try to access the Internet.

I had previously done everything you suggested except unplugging everything at the end.  I also set my WAN IP manually due to the configuration of my AT&T modem for a pseudo bridge (pass through) mode.  I do not require PPPoE.

 

Upon trying again, I am noticing that when I update my bandwidth for my speeds, the setting does not seem to stay.  I set for 1000/1000, but whenever I go back to the bandwidth setting page it still says 100/10.

 

This is getting beyond frustrating.  My internet refuses to work unless I turn off super turbo mode and cripple my gigabit speeds.  As per the screenshot, you can see that while I am getting a fast connection, it is far from what I am able to get with a traditional router setup.  With a traditional router setup I average 900/900.  I understand that the R1 hardware might not get me quite back to that point but 500-700 does not seem unreasonable.  This is unacceptable and needs a resolution!

Are the devices where you cannot access websites using Super Turbo Mode connected to the Orbi, connected to the Netduma, or connected to the Netgear? If you try this on devices connected to different routers, are you able to access websites on some and not others?

 

In set bandwidth, enter 999/999. Also change the Netduma router time to your time-zone if this is not configured already. After that, please try the optimisations from this guide - specifically EEE: https://helpdesk.flexradio.com/hc/en-us/articles/202118518-Optimizing-Ethernet-Adapter-Settings-for-Maximum-Performance

It's every device regardless of what it's connected to.  I cannot use the internet at all when Super Turbo Mode is enabled.  I also don't see how your link to the guide you recommended would be relevant for devices that do not rely and/or do not have the settings described in that guide, such as smartphones, tablets, etc.  As for EEE, this was already done months ago on relevant devices.

 

The time was in fact set incorrectly so now that's fixed.  As for your suggestion of setting the bandwidth to 999/999, when I did that, the problem occurred yet again.  I unchecked Super Turbo Mode and everything is working again, albeit at crippled speeds.

Try removing the other two routers, so that your setup looks like: Modem > Netduma > All devices. With this setup, can you still not access those websites with super turbo mode enabled? Do you still not get your full speeds? This will likely be the main step to rule out your setup being to blame for this issue.

 

I've personally asked Iain, our CTO, regarding this super turbo mode issue. He is adamant that those issues should not be caused by super turbo mode, so it's important that we rule out every other possible cause.

[DarkCentauri777]

I have gone ahead and exchanged the router, mostly for troubleshooting purposes.  I should have the replacement tomorrow.  If that does not work, I would be at a loss as to what other device would cause this issue.  I've never had a problem until I started using the Netduma router.

 

Has the possibility been brought up that enabling Super Turbo mode could possibly be affecting another setting?  If all the setting does is disable congestion control, then I would imagine that some of my devices can connect, and some cannot.  But this affects the entire network.  I'll update tomorrow when I have the replacement.  Unfortunately I am not in a position to either eliminate or replace everything on my home network to isolate this issue if it comes to that.

[Netduma Fraser]

Okay let us know how you get on with the other router. If you don't have the same issue I am happy to look into the issue in a 1 on 1 with you next week sometime. 

 

All super turbo does is disabled congestion control, so really its not affecting the network traffic at all, other than basic routing. 

[DarkCentauri777]

The replacement router has arrived.  The same problem occurred.  Before I had the Netduma, my connection was setup using the Netgear switch to basically bond the ONT and my personal router's WAN port via VLAN, effectively bypassing AT&T's device after the initial connection. (Pace 5268AC) as documented here.  It involves setting up a VLAN.  I followed your suggestion for configuration, which for me involves doing what is documented here.  The only thing I can think of is that there is something about the Netgear switch that is not allowing the full connection to be utilized when configured as previously linked.

 

My setup now goes from ONT > AT&T WAN port > AT&T LAN port (configured in DMZ+ Mode and its WiFi disabled) > Port 1 on Netduma, with my PC, XB1, Netgear Orbi and Netgear switch connected to it.  WiFi on the Netduma is disabled. I am now able to use the internet and utilize full speeds.  

 

While this setup does work. it unfortunately has introduced some new issues which I don't think are specific to the Netduma, but I am unable to find a feature or 2 that could prove useful for my scenario.  For instance, I would like to be able to utilize port triggering.  My cell provider uses WiFi calling, which is now being blocked somehow.  I would like to be able to trigger the ports I need so that when the phones need them, they can be opened.  Port forwarding only allows 1 IP per port range.  This also might be related to another issue that has cropped up.  On Xbox Live, I am unable to use party chat.  I get a message that says "Your network settings are blocking party chat", with an error code.
