G+_Jason Perry Posted September 2, 2016 Share Posted September 2, 2016 So my father has a reoccurring problem. He is on a rual wireless Internet connection. His ISP keeps locking him out of their network; because, something on his network keeps reconnecting to their RADIUS server and getting a new IP address. Every time this happens it eats through their address pool and they have to kick him off. I do not know too much about PPPoE connections, so, I was wondering if someone who knows more than me could offer suggestions as to why this might happen? I have a 3 ideas why this might be happening, but I am interested what the community has to say to see if any of them overlap. Here is a quick diagram.

G+_Ben Reese Posted September 2, 2016 Share Posted September 2, 2016 I could be wrong, but I think if something is eating IPs it would have to be either the router or their wireless modem. I'd check to make sure the cable from the Tango wireless box is plugged into the WAN port of the TP-Link router and not a LAN port. If not, the WISP could be crazy enough to give every device on the network a public IP. And if every device on the network has a public IP, I'd assume the XP machine has already been pwned (and maybe the printer too). That really seems unlikely though.

G+_Jason Perry Posted September 2, 2016 Author Share Posted September 2, 2016 Ben Reese?, that is one of my assumptions, the first time it happened (Nov of last year) the ISP said it was the router. I bought the current one and it happened again early May of this year. I called the ISP and reset everything. The end of last month it's happened again. I tested the cable going to the radio with a simple tester and it seems fine. My one thought is its the power was cutting out as it is a rual area.

G+_Travis Hershberger Posted September 2, 2016 Share Posted September 2, 2016 I'd be suspicious of the TP-Link router initially. Is the old one still around that they could try? It's a little more expensive, but the combination of a Ubiquiti EdgeRouter X and UBNT-AC-LITE is the rock solid, unbeatable combination. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted September 2, 2016 Author Share Posted September 2, 2016 Travis Hershberger?, I would love to put in an EdgeRouter, and eventually I hope to. I have the old router lying around. In May I had it at the end of the 250ft run, I thought having it there could be the issue and took it out. I didn't think it was the problem in the beginning and still don't. If the issue happens again maybe I will have to try it. The problem is it has only been happening every 3 to 4 months. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted September 2, 2016 Share Posted September 2, 2016 Weird that they would pin it on you. Would be nice if they could tell you the MAC of the device eating IPs. They should probably limit each modem to a single IP anyhow. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted September 2, 2016 Author Share Posted September 2, 2016 +Ben Reese, their words, because it is behind a NAT they can't tell where the problem is coming from. I think the radio is as far as they can see. It's IP doesn't seem to be accessible to me, but I know it has one. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted September 2, 2016 Share Posted September 2, 2016 So who owns the CPE? If it's their device that connects to their wireless network, and it's getting multiple IPs on their network, THEY have a problem.Problem with that is that they're probably about as good as my local WISP, who can't seem to figure out how to configure their devices. If the CPE is the customer's, then it's unfortunately going to be on the customer to determine why multiple IPs are being fetched. Since it only happens after lengthy uptime, I'd put a timer on the outlet the POE injector is plugged into. Set it to shut off each night for a while when it wouldn't bother anyone that there's no internets. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted September 2, 2016 Share Posted September 2, 2016 Hrmmm... so I don't see any "Tango" wireless CPE, but it could be Trango, only their product info shows nothing on 900MHz. Legacy equipment? If you can spy a model number or other branding, perhaps someone could find a tidbit of info for you to pass along to the WISP. A while back I took issue with a bad practice on the guest wifi where my wife works, and though their IT protested that it was fine, it seems they have reconfigured to use a different captive portal system and a standard private subnet.

G+_Jason Marsh Posted September 2, 2016 Share Posted September 2, 2016 Definitely legacy equipment. Probably about the same as this ... rock2000.com - bit.ly/2cwNQhZ Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted September 3, 2016 Author Share Posted September 3, 2016 Jason Marsh?, your right it is Trango, I have been told it is legacy hardware, and my father does own it. I did have a pdf on it at one point I am looking good for it again. The default configurations on the pdf I had for the radio did not get me any further to knowing what the issue was. The ISP changed the radios configurations so I don't have access to the landing page that gives me data like signal strength. Link to comment Share on other sites More sharing options...
G+_John Saunders Posted September 3, 2016 Share Posted September 3, 2016 Jason Perry if your father owns it, how is it the WISP can reconfigure the radio and lock certain diagnostic tools on it? Sounds like an overreach on the WISP. If they want you to fix the issue, they should give you total access to the radio. That's like a client coming in with a dead laptop, no charger and saying, "I'd like for you to fix this windows issue I have, now." Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted September 3, 2016 Share Posted September 3, 2016 John Saunders unfortunately, I have to disagree. It's pretty common for the ISP to push configurations to the modem - even if the customer purchases it. I have very little experience with wireless providers like this, but every DSL and cable service I've setup has had configurations pushed by the ISP. That said, I've also always been able to view the configuration on 192.168.100.1 and that usually works on modems owned by the customer or the ISP. I've used the modem logs several times to "short circuit" Customer Service who seems to always think you need to reboot your computer, router, modem, refrigerator, TVs... "No, this modem says it can't connect to your server. This has nothing to do with my printer." It also helped when I was paying for one speed with Time Warner and my modem was configured to limit a bit lower. Good luck, Jason! I wish I knew more to help.

G+_Rud Dog Posted September 3, 2016 Share Posted September 3, 2016 If your LAN devices were to say be acquiring IP addresses, in an attempt to address this suggested possibility, toss Wireshark on your LAN and answer that questions immediately.

G+_Jason Perry Posted September 5, 2016 Author Share Posted September 5, 2016 If the IP for the radio was 192.168.100.100, would it still be a 24 bit address? Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted September 5, 2016 Author Share Posted September 5, 2016 There is a "switch" in the firmware to turn the browser interface off too. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted September 5, 2016 Share Posted September 5, 2016 Is that the WAN address of the device, or the LAN address? If it's the WAN, you'll need to check with the provider about whether it's a /24 or /18 subnet, but I'm betting it's a /24. The LAN can be configured any way you want, within the capabilities of your router. Want to use a /8 address space for your LAN, go right ahead. Make it a /30? Sure. I suppose the firmware loaded on the device is the latest available? Or are you locked out of it and still can't check? And don't flip that bit to turn off the web administration unless you can/want to SSH in for management. Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted September 20, 2016 Author Share Posted September 20, 2016 Just got a phone call from my father's ISP. They just told me that they just noticed the issue we have been having for the past year isn't the router. When they took a closer look at it there has been a brief signal loss followed by the router reconnecting. In their words the signal loss is so brief it looks like the router is just reconnecting on its own. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted September 20, 2016 Share Posted September 20, 2016 Isn't that fantabulous. I wonder what's causing the interference. Have they said , or are they blaming their equipment or his? Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted September 20, 2016 Author Share Posted September 20, 2016 No official reason yet. Personally poor radio placement. It is in the easiest spot where they could get decent signal. Now all the trees that were in the way before are bigger. Link to comment Share on other sites More sharing options...
