I bought it for AUD$50. The closest router in terms of price + power was a TP-Link for around AUD$70 and it still was behind on features.
I did tried dd-wrt for this same purpose, the interface is much better, it is very flexible as openwrt, but I couldn't put my wifi on client and AP mode at the same time and I needed to connect to one of my WAN using wifi because that modem is not close enough yet.
BUT OP will only double his bandwidth if he is purchasing a rate less than or equal to the actual realized throughput of his WiFi connection, somewhere from 50-90Mbps.
Additionally, all Cable modems have some kind of throttling because the speeds offered by ISPs (30x5, 100x8, etc.) are not evenly divisible by the per-channel rate of DOCSIS 2.0/3.0 (38Mbps Down, 27Mbps up).
And then there's this: http://www.dslreports.com/forum/r29743167-Signals-Report-16-...
A piece of coax has a finite amount of bandwidth it can carry. As modulation schemes get better (QAM256) you can do more with less.
To say DOCCIS 3 is limitless is not taking into consideration the hardware and frequency constraints. The more frequency you allocate to Internet the less is available for other programming (TV).
From my experience with low throughput 2-4mbps lines I'm deeply sceptical about claims like that. Throughput will generally be OK...but if you want stable latency...good luck. The second someone else is on the same line goes flakely unless its a high powered line (fibre etc)
I blogged about my setup at http://www.sajalkayan.com/post/fun-with-mptcp.html
I actually use this method to use school WiFi anonymously (or rather, as someone else).
It's how eduroam works, and that works fairly flawlessly (provided the routers have enough bandwidth).
"Passpoint automates that entire process, enabling a seamless connection between hotspot networks and mobile devices, all while delivering the highest WPA2™ security. Passpoint is enabling a more cellular-like experience when connecting to Wi-Fi networks."
If you want the fastest speeds on Comcast, pick up a DOCSIS 3 Motorola Surfboard modem. I'm paying for 100/20. This is what I get with my surfboard http://www.speedtest.net/my-result/4251868226
No.
I feel like this post should be longer, but I can't think else to say. The answer to your question is: No.
The only way it would increase bandwidth is if it evades artificial throttles. Having two connections to the same (neighborhood) pipe seems useless.
Well obviously. They give you a specific bandwidth for your house, you can buy more or less bandwidth if you want.
> Having two connections to the same (neighborhood) pipe seems useless.
The neighborhood pipe can probably do 100 to 1000 times the bandwidth to each individual house. So how is that useless?
Plus with xfinitywifi they allocate double bandwidth to the house, so the wifi bandwidth doesn't slow down the purchased bandwidth. (The cable modem can easily handle 10 times the bandwidth typically allocated to it.)
UPC only makes a small amount of bandwidth available on the 'Wi Free' (UPC's version of Xfinity) network, seems to be about 2.5mbps down and 0.5mbps up. In my country (Ireland), the minimum package you need to get 'Wi-Free' is 120mbps down, so It's not really worth the effort for an extra 1% bandwidth.
Possibility two: placebo effect.
Apart from that, my understanding is that Comcast routers broadcast your network and also broadcast this comcast hotspot network, and they are metered (and presumably capped) independently. So with this hack you would use only your equipment, you're just taking advantage of both networks that are being broadcast by your router.
Check the article again. The author is connecting his router to his neighbor's hotspot.
I don't have a lot of confidence in Comcast to have set it up so that connections to the xfinitywifi network do not impact the regular, private usage. It's just not in that company's style to think proactively and conscientiously about its customers.
Does anyone know if this OpenWRT works? I would love to push my speed to its limits. Comcast pretty much has a monopoly in my city and they are not very helpful.
If you want to get a better Wifi connection, get a good router and plug it in to the one installed by Comcast.
If the grocery store makes a big deal out of having staff to carry groceries to your car, and how they sell 120 groceries, they had better be able to carry all 120 to cars that support it.
Wifi is extremely finicky, due to interference and the FCC's limits on legal transmit power levels. But you should be able to get same-room speeds of at least 180 megabits if you have a decent router and a client that supports it. The key things are you need to use a 5 GHz radio and (for distance) channel numbers >100. Many ISPs still give out 2.4 GHz-only radios, so performance will suck.
Either buy a Cat5e/Cat6 cable or change your wifi access point to use 802.11n. I am connected to my 2007 Airport Extreme at 300mbps right now using 802.11n.
This has more information on cat5 vs cat5e vs cat6 and their compatibility with different speeds / modes: http://serverfault.com/questions/107172/what-is-the-actual-d...
TL;DR almost any Ethernet cable you buy today will be cat5e or better, which will work just fine. Really old cat5 is technically compatible and should work too, but due to it having slacker tolerances for e.g. crosstalk, it might not work over e.g. longer runs or difficult situations (cable ran next to fluorescent lights, etc).
EDIT: If you want to know what speed your link-level has established, your OS should provide this info. netstat -e on windows or netstat -i on OSX / Linux should show the connection speed. In windows, you could also do WinKey+ r -> ncpa.cpl -> right-click active internet connection -> connection details IIRC.
I imagine the less technically-inclined would have given up a lot earlier in the process.
In fact I've noticed conveniently broken web pages from multiple large corporations. I've ran into this issue when attempting to access privacy policies and other disclosures.
There certainly may be something nefarious about this. Comcast could certainly get away with it.

Also, because your router is a routed client of the xfinity wifi network, I'd imagine there'd be a big increase in latency. It'd be interesting to see the before/after speed test results.
My service is 3Mbps. My modem & my hardline are both capable of much more, but I only pay for 3Mbps so I only get 3Mbps. I think this trick is basically allowing the author to tap into the unallocated extra modem & line capacity that is currently used to feed xfinitywifi.
The best way to improve consumer Internet connection is to get a fast router that can route fast in hardware. I'm always amazed people think a SOHO device doing WiFi, NAT, DHCP, DNS, etc. on gimped hardware is "fast". The majority of time it's not and real improvements can be realized with dedicates hardware. Meaning that until you split service off from routing using cheap, consumer SOHO gear, will most always be the bottleneck.
He isn't connecting to the same modem twice.
You seem to be dripping misplaced condescension all over the floor - would you like me to fetch a mop?
I just bought a TP-Link TL-WR841N and it has no problem maxing out my 30mbps connection, even with some extra LAN traffic.
I'm a big fan of my TP-Link WDR4300. I can easily max out my 250/60Mbps uplink while it's also doing NAT and some light firewalling, in software. It also runs all of my IPAM (DHCP/DNS). Additionally, it also runs OpenVPN (and can do ~20Mbps of encrypted bandwidth) and a BGP session (using Quagga) over that VPN to my local hackerspace. All in a single OpenWRT device that's sub $70.
Is it equivalent in performance to a hardware router? Of course not. But these start at a few thousand dollars (even Cisco ASA and Juniper SRX class hardware does its routing in software...).
I like the idea but I wonder how it performs on many use cases (like Skype or online gaming).
from http://wiki.openwrt.org/doc/howto/mwan3
Linux outgoing network traffic load-balancing is performed on a per-IP connection basis – it is not channel-bonding, where a single connection (e.g. a single download) will use multiple WAN connections simultaneously
I can still easily imagine a conflict where your signaling IP and your media IP are different in VoIP, but binding connections to IP addresses is pretty reasonable.
I don't see anything particularly noteworthy here. He just happens to have a very specific setup and is leveraging it.
I live in a typical neighborhood in Chicago; houses are spaced apart enough to where you don't get a ton of wifi overlap, but enough to see a handful of your neighbors networks. I noticed the first "XfinityWifi" network about mid/late last year and now will see between 2 - 3 from my house. I found this post interesting because of how he is leveraging these, relatively, open connections.
"When you rent a cable modem/router combo from Comcast (as one of my nearby neighbors apparently does)"
It may be illegal:

Comcast is not on the EFF's list of Wireless Friendly ISP's (referenced in the Wiki article):
https://www.eff.org/pages/wireless-friendly-isps

It has been proven that in many places at least in the US, it is illegal and in some cases is a felony.
