Hi everyone,

I have been running into a problem for the past three months now and have been unable to get it resolved through technical support. I've gone all the way to have the network admins look at this and hit a road block.

So I am looking for your help!

I utilize the Linux kernel archives for my work (which is at https://git.kernel.org/). It is a completely legitimate site that hosts the source code for Linux. However, I am unable to access the site from my Exede internet connection. When I VPN I am able to access the site but the transfer speeds are so slow it makes it virtually unusable.

Here is where you come in, the network admins (via tier 2 technical support) can access the website through there test deployment. I am wondering if you guys can help me verify that it is in fact something specific with my modem causing the issue.

Are you able to access git.kernel.org on Exede? It might help to post in what rough geographic area you are on too in case this is a geographic issue.

For you networking folks, I am able to do a ping and trace route successfully when using a VPN but my pings are blocked and the trace route stops out once getting to the IP block of kernel.org. Additionally, my DNS resolves to the same address when connected directly with Exede or when connecting via a VPN.

Thank you everyone!

Accessible on Exede from California, San Jose area, beam 369.

The last sentence of your post has a problem.  Exede hijacks all DNS  request  made to other DNS servers.  Your VPN should be able to get you there because it's the method of escaping the Exede DNS.

The mystery deepens when you can't go there with Exede, but I can.
 
If you are running Windows it could be an entry in your host file. I was going to post mine but I see it's actually copyrighted by Microsoft.  It has only comments (lines preceded by #) and nothing else.

So I can confirm that the IP address is the same if I am on Exede, accessing through VPN, or offsite.

I am getting the same issue on all the devices at my house, two Windows 10 computers, a Linux box, and then two Android devices.

I am going to try this at a neighbor's house (who also has Exede) to see if I can access the site there. They should be on the same beam, so that may help further isolate the issue.

Then the only thing left I can think of may be to get my modem replaced but you wouldn't think that would be an issue.

I also tried putting one of my computers on the DMZ with my Exede modem / router and that didn't help either.

I have no problem accessing that site on beam 332. I would be looking at your firewall and host file for the problem. It isn't the modem or router if you can connect to other websites.

I had the same problem with another site. I couldn't access it from Exede on any computer or device but all would from other internet sources. I posted about it on the other Exede site and everyone that tried could access it from their Exede although I never found anyone from my beam to try it. I never did find a solution.

Thanks Bev for checking.

I have tried on all my various devices while plugging in directly into the Exede router with essentially the default settings and I get the same result.

Okay, interesting.. my neighbor can access the site. So I don't think this is beam related. Just in case, what plan are you on Jim16? I'm on the Freedom Plan.

Joshua, I am on beam 314 in southerntier of New York state. I am on the Freedom plan. When I tried to go to the site, it would not connect. This is what was reported.

Can’t connect securely to this page

This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.

I'm also on the Freedom Plan.  I don't use any outside AV or firewall, just what comes with Windows 7.

Okay, Jim & Steve, I have confirmed that changing my local network configuration away from the default 192.168.1.0/24 in my router settings is what's causing the issue for me. I was using a 192.168.30.0/24 configuration (i.e. modem IP at 192.168.30.1 with a subnet mask of 255.255.255.0).

I can change the settings and like clock work I can reproduce the issue.

My closest guess is that this is some sort of bug on the modem as it relates to static routes and the transparent proxy on the modem. If you guys do have issues accessing any other sites, I would recommend trying this as a work around.

Jim and Joshua, what AV and firewall do you each use? This is looking like an issue with one of those, possibly you have the same one. If not that, then need to compare host files and find the problem, it may be there.

I use Webroot with Windows Firewall but I have the same problem on my Linux machine (no firewall or AV software) and also on all my Android devices as well.

This is what's leading me to believe it's not related to AV or Firewall software on a specific device.

FWIW, can access on Beam 329 in Virginia, but I had a similar issue with a single site long ago and far away using an older router I had at the time. I eventually wound up doing a hard reset of the router to its default and it wound up correcting it - resorting to the paperclip was a drastic measure but worked for me.

I am heading out for the Thanksgiving holiday but that's my next step as soon as I return is to fully reset my modem / router with a paper clip.

I bet it makes no difference,  mine didn't. That was one of the first things I did, plug a network cable directly into the modem.

Okay, I am posting an update. I'm back from the Thanksgiving holiday and I can report that a full reset of my Exede modem resolved the issue.

I am a little surprised because the settings on the modem itself are essentially the same. I am wondering if the full reset cleared out some sort of cache that was causing the problem.

At any rate, for those of you who are experiencing similar issues, I thought I would post what resolved it for me.

Posting a further update..

Changing my local IP configuration from 192.168.1.0/24 to 192.168.30.0/24 seems to be causing the issue. I am a bit baffled by this and will continue to experiment and post a further update.

Furthermore, I noticed a difference in the DNS name resolution. Why this would be with changing my local IP configuration I'm not sure. Unless, subsequent reboots are giving me different DNS? Anyway, more to follow.

Yes, Exede uses a dynamic IP address so, you need to allow for that. You do not have a static or even persistent IP address with Exede service unless you have a Business account, then it is persistent but not static.

Oh, sorry, I should have been more clear. I was referring to the DNS lookup results for the site I am having trouble with.

Here is what I am seeing by looking up the IP address of git.kernel.org via the following command in a Command Prompt 'nslookup git.kernel.org'.

When using 192.168.30.0/24 for my local network:

Server:  99-196-99-99.cust.exede.net
Address:  99.196.99.99

Non-authoritative answer:
Name:    pub.ewr.kernel.org
Addresses:  2604:1380:1:3600::3
          147.75.196.57

When using the default, 192.168.1.0/24 this is what I see

Server:  99-196-99-99.cust.exede.net
Address:  99.196.99.99

Non-authoritative answer:
Name:    pub.sjc.kernel.org
Addresses:  2604:1380:1000:8100::5
          147.75.202.151

You'll notice that the results are different, even though nothing has changed except the local network configuration. For reference, this is under Router Settings -> Advanced Settings in the Exede Router's configuration site.

At any rate, leaving the default is working as a work around for me but I think this points to a bug in the router firmware. I am going to call technical support and see what there thoughts are.
