I hope this is the right thread for this. Here's how my house looks:

WRT54GS on latest tomato
Mac mini on G
Dell laptop on G

The mac mini is basically a torrent workhorse. I can usually get 1.3mb/s down running a bunch of torrents. What bothers me is that when I go to copy a file from the mini to the dell over SMB, the transfer starts at 100kb/s and slowly ramps up to 500kb/s. I can't move the mini into a better reception position but I know it can do 1.3mb/s down and I think 800-900kb/s up. I have the dell laptop right up to the router antennae. I'm also use an antenna relocator for the router with ~15.5" aftermarket antennas.

Should I be happy with 500kb/s or is that really lovely? It makes streaming SD movies a chore sometimes when the variable bitrate jumps.

Why is nobody on channel 14?

Edit: Oh...

I switched to channel 14 and my laptop still worked making me think it was best thing since no one else was on it but then I checked my other machines and they all can't use it :(

When the channels get crowded the channels will tend to jam each other. If I copy large files over wireless I can easily jam 80% of the available wireless spectrum. All this means is that everyone's wireless tends to get significantly slower.

So the poor guy above with his wireless on the same channel with two other wireless networks is getting slowed down by their activity and slowing theirs as well.

So inSSIDer graphs the channels as overlapping. Does that mean that if channel 4 and channel 6 are super crowded, channel 5, in the middle, will be affected despite it being pretty open?

Just for perspective, to saturate a 10Gbit connection with a file server, you would need about 4 top-end SSDs all going doing reads at full steam. Assuming your motherboard's storage controller could even handle that, that is. You could almost run a graphics card over ethernet with that kind of bandwidth.

Yeah but it's not like there's any good options in between 1G and 10G in the consumer space is there?

Most consumers couldn't even saturate 1Gbit more than very occasionally, especially since so many devices are wireless and therefore confined to the 50-300Mbit range.

Well I'm not talking about your average consumer but towards the extreme end of what would technically be considered 'consumer'. For instance, small businesses that cannot afford enterprise level networking. Independent/Freelance digital content creators, etc.

Link aggregation/LACP won't improve the performance of one client to one server communication (unless a layer 4 hashing algorithm is used, available on some switches, and multiple connections are created between the client and server). It's useful for one-to-many, many-to-many, and redundant connections, though.

So if I did need those things 10G is the only option then?

How about thunderbolt? If your other machine is near you, that's a 10gbit connection no? I guess there probably isn't software to do this yet. You'd have to wait until 2012 before the hardware is available for non macs (or buy new macs) though. Hopefully their fiber optic cables actually come out as they are promising 100meter runs.

DOCIS 3.0 allows you to break through the 42mbit barrier that caps DOCSIS 2.0

Also since DOCSIS 3.0 supports multiple channels, I have heard of people getting a good amount higher of bandwidth than what they are paying for (not true for everyone, but I am getting higher speeds than I am paying for).

Another benefit is I trust my own hardware, I don't want to use their leased stuff. Comcast also charges like 7 bucks a month to rent a modem, the SB 6121 was only like $83 shipped, it also makes sense that it will pay for itself.

Interesting. How do the cable companies control your up/down speed cap for the different tiers they offer? If it was all in the modem, you would think people would have hacked the poo poo out of that by now right?

But even if I did get an aftermarket modem, won't returning the leased modem tip them off to your shenanigans?

Edit: Lastly, what do I need to do to swap out the modem? Do I need to configure the new one with some sort of credentials for it to work? It's been so long since I did the last time.

It uses a Ubicon CPU which isn't supported by DD-WRT or Tomato.

It's an 802.11n router with built-in gigabit LAN/WAN ports (albeit 2.4 GHz 802.11n only) that's now selling for a sale price of $65 (was $99) and three external antennas which will give you MIMO capability / increased throughput (assuming you're using 802.11n wireless equipment..)

Also its firmware has a bunch of features similar to those found in Tomato / DD-WRT, such as the ability to set antenna power, QoS settings, manual settings for the WAN port (can be set to gigabit for best compatibility with DOCSIS 3.0 modems.) Also seems to have some sort of Virtual Server feature in addition to the standard port forwarding options. Another interesting feature is that it can automatically email system logs to an arbitrary / external address and has a website filter that allows you to enter URLs that will be blocked by the router itself.

I'd say it looks like a good router for sysadmin types who don't need that newfangled 5 GHz technology. You could conceivably swap out its three little 2 dB antennas for more robust 5 dB antennas for even more range.

Thanks for that. I still don't get the relationship between 802.11n, MIMO and 5ghz. Don't the client devices also need to support MIMO and 5ghz in order to take advantage of them? Don't they also need multiple antennae as well? Am I poo poo out of luck on older 802.11g laptops by just upgrading the mini-pci card since they may only have 1 or 2 internal antennae?

^^^ Thanks. This is for my home BTW. I've been using a WRT54G for the longest time. Its just been a big catch 22 to upgrade since none of my clients were n but now a few are.

To get MIMO to work, I assume I have to enable it on the router and also on the client(?).

Also, 5ghz is really only useful because 2.4ghz gets crowded? But it has a shorter range and is affected more by walls and obstacles?

Unless your wireless network is hanging on by a thread, you won't notice a difference. Instead, you should look into an internet service with a faster upload speed. Putting it on a DMZ won't help either.

No trouble, just want better latency. Anything wrong with using the DMZ over port forwarding for XBL? I figure there's no harm and less work for me and the router.

Not really a home networking question but if I've got a 10G switch with 1x10G device hooked up and 10x1G devices, will the 10G device bandwidth be utilized beyond 1G if all the 1G devices start communicating with the 10G device at the same time? Does anything special need to be setup for this to work?

This is a dumb question but it should be fine to plug a switch into one end of the powerline adapter right? With 4-8 devices attached to the switch sharing the bandwidth over the powerline? Shouldn't really be an issue since the powerline adapter's peak bandwidth should still be less than my broadband anyway and realistically I'll only have 3 devices active on the switch during peak times.

Sorry if this is not the apropos thread for it.

How close are we to having mainstream 10G on mid-high end workstations? As in, built into motherboards and not an optional add on? Sorry if this is not the apropos thread. I'm constantly saturating 1G at work as we keep all storage on the network but I know its not something that can be easily or cheaply rolled out. I figure having it ubiquitously on workstations and servers will drive up adoption as you're pretty much forcing everyone to buy into 'half' of the hardware requirement.

What are you doing that you're saturating 1G all the way to the clients? With the kind of massive storage and network infrastructure it would require to keep that all chugging along, how is an extra $500 per client a dealbreaker?

For the lack of a better word, 'video editing'. Its not really video editing, its compositing. Think of a 100 layer photoshop file with each layer being a separate file on disk. It doesn't have to play at realtime speed by any means but its a lot of data. Our material is 24fps in stereo so for each frame we are reading hundreds of files and processing them. We also have movie files that are upwards of 100 Mega-BYTEs per second that have to be buffered for realtime playback but thats an edge case. Most of our movie files do not saturate 1G but we also have lots of users. I'm sure there are people here who would have better answers but I was just asking in general if integrated 10G in the workstation market is a real thing thats going to happen.

edit: We do have 10G bonded(?) connections between our network storage for sure but normal people clients only get 1G.

Just installed an ASUS RT-N66U using the latest firmware (3.0.0.4.276)

Previously with an old rear end WRT-54G, I used inSSIDer to pick the cleanest channel for wifi. With the RT-N66U, should I just let the router pick what it determines to be the best channel? That kind of task seems like its best suited for a machine to do anyway. Just not sure how it works when all the routers in an area are doing it programmatically which might lead to thrashing.

On a related note, is ~2.5MB/s pretty good for transferring a file over SMB from a 1G ethernet powerline source to a G wifi destination?

I ask this every year but are we any closer to 10G at home or built into workstations? I know its a lot of bandwidth but I'm already hitting that at work and somewhat at home. Its more like the difference between waiting 10 minutes for files to copy vs however less it would be with 10G.

I feel like consumers/smaller businesses would be inclined to get 10G switches if their workstations all had it standard but not if it meant getting a NIC as well. Kinda like 1G. I didn't know anyone back in the day who really wanted to buy a 1G NIC but all of a sudden they were standard on mobos and laptops.

I know 10G adoption is slow and very few people would have a real use for it but that doesn't mean its not going to happen.

Not really. It's still cost prohibitive. 600+ dollars for an adapter and over 1000 for the cheapest switch

Just checked newegg for shits and its good to see that I got a 130 results for 10G NICs which is nice to have the selection. Cheapest Intel was $334. I'm not sure how much that's really changed over the last year or 2 though.

10G Switches are still $1k+ but I think thats come down. So if you 10G at home you're looking at $2k for 2 NICs and a switch at the minimum. Guh. I'd be in personally if it were ~$500 although for $2k+ I could justify it if I owned a small business that lives on moving data.

Edit: oh I'm mistaken. Some asshat thought it was a good idea to keep the router on the 3rd floor of a 3 story apt with occupants on all 3 floors.

Edit2: Mistaken again! Looks like the majority of the occupants are on the 3rd floor with a straggler on the first (soon to be me). I think I might got with the netgear xwnb5201 powerline + AP. $70 after rebate at Frys!
