Windows 7: What's your Internet Speed?

The reason why you can't access the modem with the proper IP of 192.168.100.1 is because the modem is not in bridging mode. I should have saw this earlier. What you need to do is pull the ethernet cable from the router to the modem and plug an ethernet cable connected to your PC to the modem directly where the router was plugged in at into the modem. Now try 192.168.100.1 to access the modem.

Once in the modem go in and hit the Restart Cable Modem button shown in the pic. DO NOT hit the Reset All Defaults button. That would reset your ISPs configuration for the modem and you'll lose Internet access.

Once the modem is reset, go into the modem's options and find something for bridging mode. Since you're using a router with your modem the modem needs to be in bridging mode. Once the modem is in bridging mode you can now reconnect the router.

The reason why you want to reset the modem is because if you have a speed upgrade, this is generally what you need to do in order to obtain that new speed. Comcast (Your ISP) updated the profile in your modem and thus your modem needs to be rest to take advantage of it.

If you still don't get 100 Mbps on download, then try that smokping test I gave a link to. But read what I said about allowing pings in your router for 24 hours temporally. If the line is good from Smokeping then I suspect the router or modem is at fault with your bandwidth. It may even be the NIC in your computer. Does the network card in your PC use some kind of software? And if so, are there speed enhancements and what have you in that software? I asked this like twice now with no answer. NVIDIA nForce is a GPU driver, not a network driver. Run this program and tell me what it says under Network. Take a screenshot of the information and post here.

Finally, instead of speedtest.net, try SpeedOf.Me | Internet speed test instead.

Well, here's a wrench in the gears. It appears your modem is already by default in bridging mode. Motorola SB6141 in Bridged mode?? - Comcast Business Support Community

So why you can't access the IP of your modem I don't know. If it is a double NAT condition, then my instructions of pulling the router temporally from the modem and connecting directly to the modem would elevate that. If it is a double NAT condition, this could be in fact why your bandwidth is cut in half. Speculation on my part though as I would think a double NAT would just nullify your Internet connection altogether.

First let me see if you have a double NAT condition. To do this go to the Start orb bottom left and in search enter:
Code:
cmd
Now in the black DOS looking box enter:
Code:
tracert google.com
.

What does it say for the first two hops? The exact first two IP addresses.

Before you go on with resetting the modem, tell me what the tracert results are. If you see the first two IPs as a class C private IP address like 192.168.1.1 and 192.168.100.1 or something like that then you have a double NAT. To elevate this, plug the ethernet cable from the modem to your router's LAN port rather than the router's WAN port.


So router's LAN port to modem.

Not router's WAN port to modem.

Thank you VERY much for the troubleshooting tips. But before I do that, speaking of things I should have mentioned, I'm using a VPN. I disconnected it and the download speed is 100Mbps. Reconnected it, and it drops to 10-45Mbps DL, and the double VPN is only getting around 3Mbps DL.

So does that tell us the modem and router are working as designed? If it is, does the troubleshooting shift to the VPN, or is the speed drop due to the VPN usually that severe?

Good grief, man. You should have mentioned you were using a VPN from the get go. Yes, a VPN will slow your connection down. That is inherit of a a VPN. The VPN I use actually doesn't have much of a slow down at all.

You may want to run that command and still make sure you don't have a double NAT. If you do, try plugging the modem to the LAN port of the router instead of the WAN port of the router. Go back and read my instructions on running the tracert command. Disconnect from the VPN first.

As to VPNs, you need to know a few things about those. I've written a post on my own forum about that here: https://cyberpcforum.com/viewtopic.php?p=1491#p1491

Also, you have to have a certain sense of blind trust in the VPN and if they adhere to what they say about not logging, etc.

If you have the option to use UDP in the VPN over TCP, then use UDP. That would be faster. The location you connect to would also have a bearing on speed. As well as how many people are connected to that server.

Still here, working on some backup stuff. NordVPN says if I use UDP I won't have double VPN. I'm talking to ASUS for help setting up a VPN on the router. Hoping to use that in addition to use them in series...?

NO! Do not setup a VPN in the router. And You don't want to use the VPN client with a VPN client setup in the router at the same time. Plus, it may not even work since in effect you'll be connecting to the same IP twice which probably won't work.

You don't want TCP. Use UDP and forget about the double hop. I gave you a link on my forum about VPNs. If Nord is based in the U.S it's worthless. Plus, I bet they log.

Another thing. If you use the router full time with a VPN setup, you can and will run across sites that don't allow your VPN and I've read PayPal will delete your account if it sees strange IPs. Then to top it off, Google search and Gmail can give you hell. That's why it's best to use the VPN client on a per use basis.

If you wanted to have a full time router VPN setup, I'd get another router for that. Or use the third-party firmware ASUS Merlin. Stay abreast of its updates as well. You can buy routers on eBay with ASUS Merlin already installed. Just search for ASUS Merlin in eBay. Once you get the router either reflash it, or update its firmware. I wouldn't trust someone else's flash.
