VPN issues

My VPN connection again had issues for the past couple of days. Each time tech support (1-844-275-9310) was able to fix it. I was told by the the representative today that T-Mobile hardware team is aware of the problem and has a software fix that they will roll out by May 23rd? However, she was able to put in a ticket for me to expedite the update of my device so hopefully I do not have to keep calling them after that.

Thanks for the info, unfortunately the rep told didn't know much and told me they did not have a date. I just had to return the Tmo gateway and canceled the service.  I stayed with my ISP which I got a cheaper deal for 150mbps, maybe in the future if they fix it, I'll decide.

I read somewhere that a new firmware greater than 1.2003.03.0168 would be coming out to address these VPN and WiFi Calling issues… anyone know?

iPhone’s WiFi calling will not work correctly with this 5G router, and also L2TP VPN will not work.

Help!  This is the best service I can get for my location… and the LTE previous (White Box) router worked for all these things… but at a slower rate.

Hola:

First day with Gray tower Nokia device: model: 5G21-12W-A, Versión de software:

1.2003.03.0168. It arrived at lunchtime.

I found that my speeds were variably slow even without VPN. Usually in the teens-20s for downloads. Uploads were very variable from 0.3 to 25 !  When testing locations around the planet via SurfShark VPN from 5-8pm, there were huge differences. Ping tended to be higher with farther distance from 30-200. Speeds even from the same cities varied by 300%. Never got over 42 mbps.

Via RCN in the DC area: ping 11 ms, 52 / 11 mbps,  jitter 4.8 and 0.35% packet loss via speedtest multi. Loss was zero via single connection.

Why the VPN – in case of doing any banking, like paying bills and helps to keep things more secure.

Proton VPN, free version, worked fine, but ping was in the 200s.

SurfShark VPN initially did not work. Read the prior postings here. Did the items noted below. Someplace along the way I had to change IKE2 protocol to OpenVPN TCP or WIreGuard. Used WireGuard. This was all done in the SS windows 10 software. Ping went from 52 to 54 when using SS VPN. Speeds were a bit slower 27 to 26 and 5 to 2.

First, I did the reboot via the T Mobile ISP website: http://192.168.12.1/. No luck.

Did not do the 45 second reset.

Then I found the posting about the ipv6s and unticked the ipv6 boxes for Proton, SS, and in 1 or 2 other devices.

Still had problems with SS VPN.

Hooked up the T Mobile cylinder to my TP Link wireless device via ethernet and then ethernet from TP L to laptop, then wireless to laptop. It worked. 

Then found that the T Mobile ISP Grey tower worked with SS VPN, but after I killed the ipv6.

Then I tried turning ipv6 back on, took a while to figure out how to do this. I had to turn of SS, Then checked a website Test your IPv6. (test-ipv6.com) after making sure that all 9 network adapters had ipv6 box with a check mark in them ! Had to repeat this process several times. Also turned wireless on and off a few times too (airplane mode).

Best guess, maybe the reset and the IKE2 to TCP or WireGuard did the trick, not killing ipv6.

By 11pm I checked on the work laptop and the government VPN for NIH. It simply worked without any tweaking. Lucky I guess. Fastest speeds via T Mobile and the required gvt VPN 51 40 40 (ping, DL, Upload). Was 21 52 10 via RCN and TP L wireless router.

Also did the wireguard on the SS iphone app. Speeds were wildly variable from 22-40 DL and 1-38 upload on the iphone.

I wasted a whole day on this. I really hope my long posting here helps somebody else.

Cheers…..

I made a post here that may help a few of you:

Basically, you must use the OpenVPN protocol with a TCP connection and a Static IP/Config method. I'm using it right now with almost no ping or speed difference and several web sites show my IP as my VPN's IP.

VPN issues via SurfShark (SS) are quite different this am. 

Automatic type of connection, SS, IKEv2 or OpenVPN TCP, etc is now connecting via IKEv2. However this is disabling all ipv6's. WireGuard is not working this am. TCP does work, but disables all ipv6's. Static IP vs (typical) dynamic IP does not seem to matter with regard to speed, Windows 10 laptop. Speeds around 30s for ping (up to 100 for Seattle and Chicago, from DC), 15-20 1.5-8, DL UL. I did not google "what is my ip" to make sure it matches with my VPN.

Proton free VPN, US 3, was fine today and ping was only 41 - not the 200s; 15, 4 DL, UL.

I will assume that ipv4 vs ipv6 is of no importance for most of us (

As an aside - the enormous variability of speeds without or with VPNs is again noted. Local DC area SS VPN locale had speeds of only 3 for a while, then up to 8, vs Seattle and Chicago, along with NYC static IP at 20 DL. Ten minutes later, the speeds were different again, with local DC SS VPN locale up to 20.

I tried to post a reply twice. Neither seems to have gone thru. Lost my copy. LOL.

Cannot connect via Brave browser, chrome like. So doing this via Edge. I had no issues with Cisco Any Connect on the work laptop 2 days ago. Maybe I was lucky.

Ipv6 drops out via surfshark (SS) VPN. Can someone tell us if 4 vs 6 even matters for most of us? WireGuard no longer worked yesterday. IKEv2 and TCP worked yesterday. Using IKEv2 (automatic) now on SS via Kansas City (KC). Static IP not required for SS. Using dynamic IP. Nearby VPN locations are usually slow with SS. So I have used NYC, KC, Chicago, Seattle, and a few others far from DC over the past 2 days. Could be due to vagaries of SS. Pings usually in 40s from NYC. Higher elsewhere, usually at or under 100. Speeds: DL: sometimes only 1 but often around 20. UL are all over: 1 - 5 - 10 - 25. Tested via speedtest.net. Interestingly, yesterday Proton VPN worked with 40ms or so ping, not 200s. I have no idea what physical place I was connected to (and no idea how to find out) nor which connection protocol was used (smart, TCP, or UDP), as I forgot to check protocol.

What version firmware are you on?

also, what did you end up setting your MTU to for GPVpn?

I’m running GP 5.2.5-66 so I think there might be some differences. 

When I run ifconfig I don’t have a gpd0, if appears as though on my Mac it is using gif0 and the default mtu setting is 1280 which is well within the 1420 threshold of the 5g21.

Figured it out. We apparently use advanced routing, so my gpd0 is actually utun0 and we have 2 vpn's. Each vpn requires a different mtu setting, but having found the correct numbers 1330 and 1310 it now works.
