Re: [BLUG] how to receive my own posts on this list?

Hah, it's just the difference between how much you value an enormous tech company not having detailed information with which to target ads to you and the time and money cost of rolling your own mail server and setting up effective spam filters.

I for one welcome our robot overlord. :)

Then this answers the first question to within a 95% confidence level
(for me anyway): the issue is entirely with the Xfinity. Good luck
convincing the tech of that, however.

As someone else suggested, this sounds like a timeout; either a process
giving up, or a process finally being started. I'm reminded of the SySV
init sequence, where each process comes up one-by-one. If there was a
network hiccup, the boot sequence could hang for 5 minutes while the
script slept waiting for issue to (never) resolve.

> Could someone suggest a wifi router that would be compatible with an

I suggest that almost any wireless router you pick will work as the
issue is with the Xfinity wifi, not it's ethernet. The standard setup
would be this:

Internet <--> Xfinity <--> WifiRouter <--> your machine

where the Xfinity modem and WifiRouter should talk over an ethernet cable.

If you're looking for a wireless router that's less than crap, I'd pick
one that you could flash later. You don't have to flash it, but at
least you'll have the option to. OpenWRT maintains a list that may be
helpful to you:

https://openwrt.org/
-> http://wiki.openwrt.org/toh/start

Like Mark, I'm a (proud?) owner of a WNDR3800. It works, and I don't
have to inspect it (but I generally cover my bases) to know that some
network issue is further up the line. It was ~$100 when I bought it;
not the cheapest, but a good middle-of-the-road option.

Good luck,

Kevin

I recently replaced both my modem and router. Modem is a Motorola
SURFboard eXtreme mdl SB6121, and the router is a Netgear WNDR3400. Both

Re: [BLUG] Xfinity, Ubuntu woes

Yeah, I'm aware. What's the acronym... mdi-x? Medium dependent interface?

Though it's pretty much a standard feature, I've also run across devices since that was implemented which either don't manage it properly or still just don't have it. Not everything (seems like it's usually the consumer stuff) uses the internal switching, so I still keep a couple x-overs I've made just in case.

I suggest a crossover cable in this case because it should work with one whether the device automatically switches the contacts on the port or not. Hunter's right though, there's no real reason not to try it with a regular old ethernet cable.

As a friendly FYI: 10+ years ago, the term crossover cable meant that
the ethernet cable in question had the relevant input and output wires
switched from a normal ethernet cable, so that the output of port A
talked to the input of port B and vice versa.

This was necessary/convenient if you wanted to have two machines
communicate and you did not have a hub or switch available (and a second
ethernet cable).

Since ~2005, however, no special crossover cable is needed as all (to my
knowledge, anyway) ethernet cards have built-in hardware logic to
auto-negotiate which wires are input and output upon connection.  So,
when he says "crossover cable", you can translate that in your mind to
just "cable".  (Unless of course you're working with hardware older than
2005!)

Kevin

Re: [BLUG] Xfinity, Ubuntu woes

I'm thinking that the big time delay before it gives me real connectivity has something to do with some sort of protocol/program that is running, running, running, then finally timing out. If so, it's blocking my connectivity.

BTW, thanks for all your help for this Indiana newbie!

I have zero experience with that hardware, so take what I have to say with a grain of salt, but I presume you can connect to one of the Ethernet ports with a crossover cable into a wireless router and just use it as a modem. That should work unless Comcast is doing something really wacky and/or obnoxious with their hardware. I imagine you'll want to ask them if they can disable the wireless radios in the box to keep it from interfering before buying something for yourself.

 

I personally like the Asus and Buffalo wireless N routers. I've had good luck with both. I've been using a Buffalo Airstation N600 running their DD-WRT firmware setup at home for the past 3 years or so with a Motorola Surfboard modem and haven't had a single problem with it since I ditched Comcast's modem to use my own. Lots of nice features come with DD-WRT as well if you're willing to dig into the technical stuff.

 

Another thing to consider if you think the XB3 is the source of your headaches… If you're paying to rent the XB3 from them it might be worth it in the long run to invest in your own modem. I was paying $6 a month to use their basic modem (Motorola SB5100) before I bought my own, so that's $72 a year. I bought the Motorola Surfboard SB6120 for $65 shipped. It's been consistently faster (DOCSIS 3.0! Whee!) and more reliable and it's still going strong 3 years later. The downside is that you'd be responsible for it yourself. If something goes sideways Comcast can use the "your hardware's probably causing it" excuse to get out of support. I got to hear that from them once before I bought my own modem to replace their leased junk modem. Not fun.

 

Just something to think about.

Re: [BLUG] Xfinity, Ubuntu woes

I have an X201 as well but it runs Windows 8.1. When I first updated it
to Windows 8.1, I also ran into this weird problem that sometimes the
wireless connection stopped working after waking up form suspend or
hibernation. The following solution seems to help (and judging from your
reply, it might related to this problem. Thus see if the Linux driver
has this option or not):

http://answers.microsoft.com/en-us/windows/forum/windows8_1-networking/windows-81-dropping-wireless-connection/88ef2187-38f6-436b-bc25-e92cf6fe05af

I have a Motorola SURFboard SBG6580 that is 3-in-1: 1) cable modem, 2)
with 4 1Gb ports and 3) wireless AP. Works pretty well with a large
range of wireless equipments.

Re: [BLUG] Xfinity, Ubuntu woes

AFA "did something," it was the Comcast tech who "did something" on his end. No Comcaster has seen or touched my machine.

At this point I've noticed it simply seems to be a function of time: I wait, say, 15 minutes . . . and it suddenly works. All the while, though, the connection icon is lit, saying I'm good to go. But yeah, wait ten, fifteen and it works. Disconnect, reconnect, works immediately. 

Could someone suggest a wifi router that would be compatible with an Xfinity XB3? I tried my old Quest PK5000, but it's a DSL modem.

Re: [BLUG] Xfinity, Ubuntu woes

Blanket statements like "your wifi is not as fast as our wifi" are laughable at best. There's no magic Comcast wifi protocol that works better.

The only people I would trust are the technicians that show up at your door, and even then not all of those folks are as sharp as one would hope, but my personal experience with them has been very good (both AT&T and Comcast techs).

Re: [BLUG] Xfinity, Ubuntu woes

Also worth noting is that Comcast tries to do some things with their "free wifi-routers" that I find to be suspicious and you have to jump through a bunch of hoops to be able to run your own router -- you have to specifically request that they convert the provided router to a bridge. I've had some serious issues with the provided Comcast WiFi stuff (not just in Linux) and in every case, I've ended up disabling the wifi on the Comcast provided device, getting them to enable the bridge mode, and running my router.

Comcast alleges that this slows down your wifi. Perhaps. I don't have a baseline to test against. I know that in my house, we are able to comfortably run 2 netflix streams and a hulu stream simultaneously.

Are you using the router from Comcast? If so, do you have access to a different router?

In context of the second sentence, it's not clear to me whether you are
talking about the Xfinity hardware, or your laptop. Did the Xfinity
support personality help you with Linux on your laptop? If so (and I
gather from the other messages in this thread that they did), then I'm
impressed, as I'm not aware of too many Linux support options for the
desktop (okay, laptop) user.

I'm also curious: you say they changed "something". How did they do
this? Did you give them root access to your machine?

For debugging purposes, it's important to describe what you mean by
"wouldn't work". Does the network just stop responding? For example,
are you in the middle of downloading a web page which stops halfway
through, and then you note that you can't do anything (open any other
website in another tab, ping a google.com, etc.)? Does the
NetworkManager applet animate as if it's unable to connect to a network?

In a later message, you pasted some lines from the syslog. I think some
bits are missing from each session, which may be important for tracking
down the issue. Nevertheless, I do note one difference:

Bad session: NetworkManager[1525]: <info> Policy set
'HOME-2D4F-2.4' (wlan2) as default for IPv4 routing and DNS.

Good session: NetworkManager[1525]: <info> Policy set
'HOME-2D4F-5' (wlan2) as default for IPv4 routing and DNS.

Given just this difference, 2.4 vs 5, I wonder if there is a mismatch in
either the Xfinity implementation of 802.11n ("Wireless N"), or -- more
likely -- is the wireless N driver incomplete on your X201? In other
words, given 802.11n, it is _not_ strange that it wants to use both
frequencies (recall that 802.11n is a MIMO technology), but I wonder if
the implementation is buggy. Specifically, I know that Intel wireless
Linux drivers had, at one point, some issues with 802.11n. Do they still?

> Then I'd put it in suspend, come back . . . and it wouldn't work.

Notwithstanding my above question, this general behavior echoes
experiences I've had with some wireless firmware and kernel modules. In
the end, my solution was to remove the module, and reinsert it. Since
your lshw output suggests you use iwlwifi as your wireless driver,
here's the relevant action from the command line:

$ sudo modprobe -r iwlwifi
$ sudo modprobe iwlwifi

This is the moral equivalent of rebooting, but at the driver level. At
this point, if it doesn't "just work", you should be able to restart
NetworkManager (sudo service networkmanager restart). That simple trick
has fixed 90% of my wireless "stopped working randomly or post-suspend"
issues on Linux.

WAG: disable anything related to IPV6 in both the computer and the router.
