Hello,

 

Earlier today, I posted about my switch to TrueOnline yesterday and asked why the download speeds of some of my devices used are up to 4-5 times faster over Wifi than via LAN cable. Whilst this question was more out of curiosity and the desire to learn more about these "things" without it having a real impact on how I can use the internet, I am now facing an issue that actually does give me some headache as it negatively impacts the network´s usability.

 

Here´s what is happening:

 

Whenever I use a VPN connection on my Mac (via WLAN; PureVPN) whilst at the same time streaming some content on TV via the android box, within 5 -15 minutes the internet connection is lost because the cable modem/router loses its connection to the True network. The DS / US and Online LEDs on the modem/router go off (the manual says this means cable downstream and upstream are disconnected and there is no RF signal), then start blinking (scanning) and after a minute or so the network access is reestablished. This happens again and again after 5 - 15 minutes. The moment I disconnect the VPN the network connection is stable without any further modem/router issues.

 

Can it really be that the use of the VPN results in lost network connections and the modem to "crash"? Or is my observation so far (VPN on --> crash, VPN off --> all good) just pure coincidence? After all, I´ve been using the new modem for just over 1 day. But since this happened yesterday and has happened again today I wonder what might be at play here. Is that a known issue amongst the regulars / pros here on this forum? Any advice as to what I should look at or do to fix this issue (other than just avoiding using a VPN)? I will certainly play around with it again tomorrow and see if I can reproduce the crashes and I will also run the VPN without the android box at the same time etc etc. But I thought I might as well ask the community here for some initial thoughts and comments. 

 

Thank you!

DUS

A packet is a packet, is a packet.  All packets look the same to a router.

 

Your problem is TRUE.

Does your modem/router has a VPN pass-through setting that's enabled?

If it wasn't set properly, your VPN wouldn't connect.

You seem to be an expert, and armchair one that is

 

https://www.cactusvpn.com/beginners-guide-to-vpn/vpn-passthrough/

 

However, VPN protocols like PPTP, IPSec, and L2TP don’t normally work with NAT.

Router VPN Passthrough technology usually allows those specific protocols to work with NAT. Users can normally easily enable and disable PPTP/L2TP/IPSec Passthrough through their router’s interface.

 

Normally, if you use VPN protocols like OpenVPN, SoftEther, and SSTP, you don’t need to worry about VPN Passthrough being enabled or not. With IKEv2, though, you might have to turn on PPTP/L2TP/IPSec Passthrough the allow VPN traffic through.

So since you refute everyone's opinion, you must be the expert.

 

We all can't wait for your professional explanation.

 

You want to share it with use, please?

Yeah, a whole bunch of Cisco Certifications and 35 years in the business, what do I know?

 

He should dump TRUE because everyone I talk to who has TRUE, hates it and complains that it is not reliable.

I use AIS Fiber.  It's reliable.  My VPN stays connected until I turn it off.  Sometimes it is running for days.  Change your internet provider.  Try AIS.

Same here with 3BB Fibre.

 

Single connection to London with testmy.net over LAN Cat5e, around 20 Mbps.

 

Same device, same test, over 5Ghz wifi over 50 Mbps with the router behind a cavity wall.

 

Using a Samsung smartphone, so that I can position myself where I get the strongest signal, over 70 Mbps

Regarding VPN. Perhaps the OP could try the free VPN incorporated into the Opera browser. See if that causes his wifi to disconnect. About 2 years ago I had a paid VPN service that stopped working in Thailand. I tried others too and couldn't get them to work. I also had a VPN service that would work for awhile and then fail. The IP addresses were being blocked.

Good point and I suspect the OP's issue is the VPN provider.  Let's face it, lots of them make glorious claims but never live up to the hype.  I recently purchased a Linksys WRT AC3200 Dual-Band MU-MIMO Router and now the VPN is on the router.  Easy to control what devices are VPN tunnelled.

I'm no IT expert, but wifi performing 4-5 times faster than LAN is really strange, even to a layman.

You may not be an expert, but you know more than the gaslighters here who claim to be experts.  WIFI has overhead that wire does not.  The WIFI speeds claimed are usually only burstable speeds.  Most WIFI cannot maintain anything near the speed they advertise.

Not one of the "experts" here responded to my comment about layer 1.

 

If your wired speeds are so slow and much slower than your wifi, I would try replacing your Cat 5 cable, or remove that heavy desk that is sitting on top of it.

First of all, thanks for all of your replies. I certainly didn´t expect my initial question to result in such a rather "controversial discussion". ????

As for the VPN causing the modem/router to soft-reboot, I still do not have a definitive answer based on my observations, today. The day started off in a way that I thought "it is definitely the VPN" because 2 minutes after starting the Mac and the VPN the modem did indeed reboot. Then another 10 minutes or so later, it did again. I thought I had found the guilty party. But that might have been the wrong conclusion because after the box had the second soft-reboot the connection was indeed stable for the next few hours.

 

Later on, I realised that my Mac was using the 2.4Ghz rather than the 5Ghz connection. A couple of minutes after I changed to the 5Ghz network, .... yep, the modem rebooted. Could the modem probably not handle 3 or so active 5Ghz devices simultaneously? After all, as many people write here and elsewhere, the Humax hardware doesn´t seem to be very good (to put it mildly). In the end, it motivated me to look for my Apple router that I hadn´t used for years and somehow I managed to connect it with the Humax, set it up and since this afternoon the Wifi as well as the LAN connections are all handled by the Apple Time Capsule. So far, so good. The cable modem has not had a single hiccup since and the speed (according to the various speed testing sites) is now significantly higher, as well. 

 

So, maybe, just maybe it wasn´t anything to do with the VPN or the 5Ghz wifi but just a poor piece of hardware used by True. I don´t know the answer just yet but it has certainly been a nice experience to go for 8 hours without the modem doing a soft re-boot. Fingers crossed that it´ll stay that way.

 

Again, thanks for your replies and enjoy the upcoming weekend.

Before you make any conclusions, may I suggest you factory reset your router/modem from TRUE.

 

Again, don't listen to Cisco certs and 30+ years in the tech business as a consultant ... what do I know?

Your experience is noted however his solution works (for now as we all know that can change diagnosing computer problems can be hard).

 

I have found that a better modem often helps as those low cost modems are not that good. I got my 3bb modem in bridge mode and an asus RT-AC86U as router and it works great. When i had just the 3bb router i had problems as the router just did not seem to handle all the work properly.

 

I do agree that its unlikely that a VPN crashes a modem connection. Though I would not rule it out completely. 

 

I really feel that often its much better to have your modem in bridge and get a decent one to be the main router if you want stability and speeds and options.

This wouldn't be the first time that an Internet Service's provided hardware turned out to be partial or total garbage (especially their NAT or WiFi implementations). As you've discovered, sometimes you're better off purchasing and deploying your own solution.

 

At least your solution wasn't one dedicating a livingroom fan pointed at the router 24/7 to keep it from overheating.

At my last house I was connected to True by my landlord. It was quite unreliable. Every night at 9 it disconnected regardless of what I was doing. Twice a month it broke. Still the landlords offspring was something at True so it may have had something dodgy about it.

 

Now I am with AIS and it is much more reliable even when using a VPN. I'm not that happy with my VPN though as it fails the Netflix test.

AIS in two places, has consistently provided the DL and UL I pay for. My VPN stays connected for days -yes, Netflix.

Not related to your ISP, but your vpn service.

 

If you want a VPN that doesn't fail the Netflix test send me a PM, you can try it out 7 day for free

I had a similar problem to this a while ago and it ended up being the settings attached to the kill switch feature of the VPN.  If your VPN has a kill switch feature, maybe check it out.

Thank you, KhunHeineken. 

 

The modem soft-rebooting *appears* to have had nothing to do with the VPN in the end. Once I installed a different router the problems stopped and I haven’t had another soft-reboot of the modem since (for 5-6 days now).

3BB 1GHz connection via their router, connected to NUC PC with CAT6 cable, 20 metres long. Never get under 800Mb/s without Express VPN or 200Mb/s with it connected to London, never cuts out except during a storm maybe, router is on 24/7, wifi works in bedroom 16 meters away through 2 walls. What am I doing wrong?   PML
