CheapDanglyHam Posted January 30, 2016 Share Posted January 30, 2016 Hi, having trouble with the Netduma. Ok so everything seems to be set up just fine, but I've noticed my connection hangs from time to time when downloading certain websites on a device or performing certain tasks on the PS4 (viewing a twitch stream for example) Upon running a test on netalyzr, it appears the Netduma is having trouble with the MTU which I believe is causing certain things to hang. I've tried auto (1500) and 1492 as that is what my Netgear router before it was set to which is the correct value for BT infinity. Using letmecheck.it MTU test, it says I'm fragmenting packets and says to lower MTU to 1484. I do that, then it tells me to reduce it to 1476 etc. The test keeps fragmenting packets. Any help would be grateful, is this a firmware bug or have I just set something up wrong? Link to comment Share on other sites More sharing options...

If so , can you try to download something and see if the same thing happens? It could be a firewall issue (possibly) , so we can try to figure the issue out by the process of elimination Link to comment Share on other sites More sharing options...
CheapDanglyHam Posted January 30, 2016 Author Share Posted January 30, 2016 Not on hand I haven't but I can have a laptop to use tomorrow. What would you like me to download? If it helps, this is the message netalyzr shows in the test report. The path between your network and our system supports an MTU of at least 1476 bytes, and the path between our system and your network has an MTU of 1476 bytes. The path MTU bottleneck that fails to properly report the ICMP "too big" is between 195.99.127.173 and *. The path between our system and your network does not appear to report properly when the sender needs to fragment traffic. I should also note I'm using the Netduma bridged with a Netgear D6400.

Do keep in mind that when Letmecheck.it runs its test that whatever numbers you're getting (non fragmented) you add 28. So if you're suggested 1472 for example, the MTU would be 1500 Link to comment Share on other sites More sharing options...
Myst1caL Posted January 30, 2016 Share Posted January 30, 2016 have the same issue mate 1492 is my optimal mtu but the netduma gives out a completely different mtu when i type it in manually here is my thread i posted about the issue a few weeks ago http://forum.netduma.com/topic/10441-mtu-issue/?do=findComment&comment=82594 Link to comment Share on other sites More sharing options...
CheapDanglyHam Posted January 30, 2016 Author Share Posted January 30, 2016 I'm thinking there is some conflict between the Netduma and D6400 somewhere. I'm going to factory reset both shortly and reconfigure, maybe set the D6400 up in ap mode? I'll post results later on. Link to comment Share on other sites More sharing options...

CheapDanglyHam Posted February 4, 2016 Author Share Posted February 4, 2016 My Internet is currently screwed. My Netgear D6400 modem/router now also has the same issue and my ISP have put it down to a fault and are in the process of fixing it. Do you have a modem router combo too? If so I'd plug it in by itself and do the following on a PC. Open command line in admin mode and run a ping test. The number after 'l' depends on your MTU. So mine is 1492 because it's a pppoe connection. Remove 28 for the headers and that gives me 1464. If the test loses packets I'd get on to your ISP. Hope that helps. Ping -n 5 -l 1464 (website address) Link to comment Share on other sites More sharing options...
Myst1caL Posted February 5, 2016 Share Posted February 5, 2016 I'm currently using the hg612 openreach modem plugged into the netduma. can't use my homehub as i get a drop in speed due to it being a homehub 5 type a and my cabinet is huawei. I don't have issues setting it manually on my asus router only the netduma. It's a very basic feature on most routers that should work. will give it another go once the new firmware is released Link to comment Share on other sites More sharing options...
CheapDanglyHam Posted February 5, 2016 Author Share Posted February 5, 2016 I'm pulling my hair out atm. Currently on hold with BT live chat. I've escalated the issue as they reckon the fault won't be resolved until Monday! Link to comment Share on other sites More sharing options...

Administrators Netduma Iain Posted February 8, 2016 Administrators Share Posted February 8, 2016 Are you using pppoe? If so I suggest you use the oroginal device by BT that did PPPoE. We only added PPPoE support for the convenience of BT customers (so they didn't need a third device). However if you're having any issues the simple solution is use the original set-up which I believe ( I've never had BT ) is : Some BT Modem > Some BT Router > Netduma > All Wired & Wi-Fi devices Make sure you disable PPPoE on the Netduma here.

Myst1caL Posted February 15, 2016 Share Posted February 15, 2016 Just posting an update to my issue sorry for hijacking the guys thread but felt we both had the same type of issue. With the openreach modem connected to the duma i get these issues it seems due to the pppoe, not sure why the duma struggles with this as it is very common on most routers these days even if it was added as an afterthought. Anyway with the bt homehub 5 on its own i get an mtu of 1488 not sure why but with the duma connected to it I get 1492 working perfect. Sounds good but with the homehub I get a speed drop due to it being th Homehub 5 Type A and my cabinet is a huawei cabinet I lose like 7mb off my download speed. Hours of live chat later being passed around from adviser to adviser and threatening to leave someone from bt finally agreed to send me the homehub 5 type b which should solve my speed issues as it uses the broadcom chipset. Allot of hassle just to get the duma working as it should but at least it will be sorted when this new hub arrives. Link to comment Share on other sites More sharing options...

CheapDanglyHam Posted February 16, 2016 Author Share Posted February 16, 2016 Will the PPPoE functionality of the Netduma ever be fit for purpose? Can it be patched. I'd personally just like a modem > Netduma setup. I just think developing a router without proper PPPoE functionality was a bit of a shortsighted decision.

HappyLittleChap Posted February 16, 2016 Share Posted February 16, 2016 Apart from Virgin cable users virtually all other UK broadband users are going to need to use PPPoE. Seems like a significant user base to consider providing a mature PPPoE solution on the Netduma. To configure an additional router with a Netduma is really going to limit your potential customer base. I think you're going to be asking too much of typical non-technical folk which will only result in negative perception and bad word of mouth.

CheapDanglyHam Posted February 17, 2016 Author Share Posted February 17, 2016 Whilst not 100% I'd imagine either on the underside of the hub itself or in the settings of the hub it'll state whether it's type A or B.

Administrators Netduma Iain Posted February 22, 2016 Administrators Share Posted February 22, 2016 Hi guys, Just skimmed over the thread. Our PPPoE works well for many many customers. The only issue I'm aware of is it has a maximum throughput limit. I don't have PPPoE to test this on but I've heard it's around 20-30mbits mark. I don't see this as an issue for three reasons: I believe most PPPoE users (which are rare, we sell worldwide not just UK) are using xDSL which is usually around those speeds The router does not have built-in hardware so there is not much you can do if you want higher speeds Finally the solution is simple just keep the existing hardware that does the PPPoE We have a lot of features we'd like to add to the router. The fact that the solution is simply using existing equipment that the user will already have from their ISP means this problem is depriotised. The original post in this tread was to do with MTU. We tested it thoroughly in the lab and it was working our end. If you have evidence please let Fraser know and I'll take a look at it after our next development cycle. But that won't be for a month or so. Again we need to prioritise tasks that will added the greatest benefits. This problem has a simple fix (i.e. use the existing hardware) so it is not as urgent. Hope you understand, and thanks for supporting Netduma. Link to comment Share on other sites More sharing options...
Pro Innocence Posted February 22, 2016 Share Posted February 22, 2016 I use PPPoe mate and get my full 60mbps down and 20mbps up. Works perfect with PA aswell now. Hope that can help this topic. Link to comment Share on other sites More sharing options...
CheapDanglyHam Posted February 22, 2016 Author Share Posted February 22, 2016 I believe the issue I was having was down to tlmy ISP in the end, even if they wouldn't own up to it. Currently in process of changing ISP. If I'm to setup as vdsl/router combo > R1 what MTU setting do I use? My MTU is 1492 so do I manually change the R1 to 1492 or does the auto function set it to the other routers value? Link to comment Share on other sites More sharing options...
