Sorry, should have mentioned that, already use Google DNS. My ISP is Teksavvy in Canada. No delays whatsoever on the wired connection on my desktop, this is solely a wireless issue.

Have you tried just using TSI's? I agree that ISP DNS servers are generally garbage but I found Teksavvy's to be much faster than Google's.

Edit: also unless you explicitly change it, android always uses google dns by default, not the DNS servers served by DHCP.

So interestingly enough, my android phone DOES use the DHCP DNS info from the router (its own address), checked it with a networking info app.

However, switching to Teksavvy's DNS servers on the router's DHCP was the magical trick! You're a genius! My phone is lightning fast all over the apartment now regardless of range. I had manually put Google's DNS IPs into my desktop too, but am changing that too despite the issues mainly being with my wireless devices.

My old ISP up until 2 months ago had poo poo DNS so I was so used to using Google. Never occurred to me that TSI might be better in this respect, turned out it was the issue all along.

Thank you very much for your help!

Huh, interesting, my nexus 7 uses google dns by default and just wrongfully assumed all android devices did that!

It's a single band 2.4ghz radio in an apartment, it's could just interference from 2.4ghz cordless phones/microwaves/other networks in the area. You could try doing a site survey (either with the router, or one of the hundreds of phone apps) and try moving to a channel that is less utilized.

Howdy,

I'm a big dummy when it comes to networking stuff and it's pretty much just magic to me how things happen.

I have a WRT160NL router and I'm getting 50 mbs when my computers are hooked up to the network and around 100 when one is directly connected to the modem. I understand that there is going to be a performance jump when it's directly connected but is there a way to increase performance over the network? Like can I get a better router or am I'm getting decreased performance because other computers ar eon the network even if they're off.

Sorry, I'm a dummy when it comes to this stuff and I don't want to buy a new router if it's not going to help at all.

It sounds like it might be time to get a new router, it's either broken or simply too old to handle your connection. A router should never be halving your connection speed.

So I have a Linksys wireless router (WRT310N) running Tomato firmware and whatever cable modem the company gave me. Every so often, my internet connection will slow down massively -- from the normal 15-30 Mbps to somewhere around 1Mbps. I can reliably fix this by unplugging both devices for ten seconds and then plugging them back in; when the network comes up it's back to normal. So this isn't a problem, really, and it's hardly unique to my setup either.

But trying to figure out why this happens is driving me insane. What on earth happens on the back end that makes the network just randomly slow down to nothing for no reason until you reset the modem and router?

Without more information (like signals/logs from your modem, or router logs), it could be anything from a bug in your router's firmware, to your modem is getting less lovely channels when it comes back up, or simply one or both piece of hardware is dying a slow death.

I have a set of Powerline adapters that are rated at 500mbps (D-Link DHP-308AV). I find that I am able to get around 60-70mbps through them in real world use.

If I go and splash out on some 'top of the range' adapters like these, am I likely to see any better speeds? Or, typically are the top end benefits mainly going to be for those lucky people who have really good cabling?

Also, I have one end of the Powerline link plugged into a 5-way power strip. Is this a bad idea?

Every now and then, the router at my place loses its internet connection. Turning it off and on again brings the connection back, 100% of the time (so I know the issue isn't with the provider or IP settings or anything like that). Would regular power cycling prevent that sort of thing from happening in the first place? Or is that type of outage completely random and just something I'll have to deal with?

I'd give more specifics, but I've had this happen with two completely different routers, in two different apartments. So I'm wondering if there are just some general principles I can keep in mind here.

If the proactive power cycling can help, what are some good options for automating that? I'm seeing some timed power strips that look good, but I'm wondering if there are some items designed with networking in mind. Also, any sort of remote control of the outlet is a plus, as I'd like to be able to reset the router while my landlord isn't home if need be.

You shouldn't be having to regularly be cycling the power on any decent router.

What router do you suggest? I just bought a POS Netgear (WNR3500Lv2) and am sorely disappointed by it. Its fine with one wireless device, and goes to hell with 3, so badly that I may as well not try using the internet. Thankfully it will be easy to return this pile.

I am considering a RT-N66U.

I absolutely LOVE my RT-N66U, it's one of the most stable routers I've owned ever, period. I am almost wishing I had spent the extra on a AC66U for 802.11AC as I feel this will be the last router I get for a long time.

I've not even bothered with third party firmwares, the stock is stable as hell, and has all the functionality I need (usable dual band, and IPv6 were my big ones).

I'm in the UK - looking at the Asus RT AC87U Wireless Router for my fibre optic connection.

Main reason for upgrading is that wireless performance, and performance through powerline adapters, isn't the best. Both my Chromecast and Xbox 360 (taking Ethernet feed from the powerline adapter) sometimes drops signal from my current BT Homehub 4. Plusnet is my ISP.

1. Would that router give me reliable and improved performance over my current setup?
2. Is the BT Openreach modem that I have separate a bottleneck? Or will it not affect my wireless and powerline performance, regardless of router?

It's a lot of money for a router, but I'd rather go all-out and get something fast and reliable than spend £40 less and regret it in 2 months' time.

Thanks for any input, I'm a bit clueless about such things.

I have the RT-N66U and it's probably one of the best routers I've owned bar none, but specific to your situation:

- Likely yes, but keep in mind if your signal problem stems from a busy 2.4Ghz band, devices that don't have 5Ghz radio will not really benefit much.
- Your modem should impact your LAN performance at all.

Powerline adapters are subject to a whole other realm of issues (bad grounding, noise, outlets being on different phases, etc), but if they're working fine now there is no reason that should change, but I doubt they won't be better. I have a pair of TP-Link ones that only hit a sync of like 100Mbps in my house.

And yes I meant shouldn't.

Today I just switched from comcast to a gigabit fiber connection. I'm using the ASUS RT-N66U flashed with dd-wrt v24-21676. For whatever reason, the router is throttling the ethernet port connection down to a little over 100 mbps and the wifi to about 35. Right into the wall without the router, it's completely fine. I've checked all the cables, tried various cables from the wall to the router, etc, but everything is fine. I'm not sure what the issue is. Anyone have any thoughts? QoS is and has been disabled by the way.

First thing I'd do is flash the router with the stock firmware, or a fork of the stock firmware like Merlin (http://asuswrt.lostrealm.ca/download), I vaguely recall ddwrt not being the best for Asus devices (can't use proprietary hardware acceleration in ddwrt). I personally run Merlin myself.

But in general you'll see a bit less than 1Gbps even after you figure out what this issue is, that router is a bit weak for full 1Gbps routing. SmallNetBuilder puts the ceiling at around 732 Mbps with LAN to WAN routing even with the stock firmware.

Keep in mind with Asus routers, ddwrt doesn't have access to the proprietary hardware acceleration, and you'll see decreased performance across the board, not just through the VPN (you don't want to do VPNing on a SOHO router though, seriously though, tried it for a client on a RTN66U, caps at maybe 15Mbps). You're much better off using merlin's fork of the stock firmware which still included the proprietary driver blobs and has support for exactly what you want to do.

Is the RT-AC66U just an AC version of the RT-N66U, with all the same custom firmware support? I can get the AC for about $135 and the N for about $105. Or the WDR4300 for $60. I do have a slight preference to Tomato over dd-wrt but as long as it is rock solid stable I don't reeeeeeealy care.

Unless there is something you KNOW you need Tomato/DD-WRT to do, I would suggest sticking with stock or using a fork of stock called Asuswrt-Merlin (http://asuswrt.lostrealm.ca/features), it's quite powerful out of the box, if it's not exposed in the webui you can telnet/ssh in and set nvram values by hand, AND you lose hardware acceleration on Tomato/DD-WRT (they refuse to include the closed source binary drivers to do so)

In the case of TWC the 6121 is all you need if you only want the 50mbps tier. The 100mbps tier does need the 6141 though. Needs and budget and all that.

Just because you don't have a need for blazing speeds doesn't mean you shouldn't get a better modem. The more channel bonding accessible to you the less likely you're to have problems with congestion, at this point BUYING a 4 channel modem is bordering on idiotic.

Antillie posted:

I agree more channels to bond is better. But even if your modem can bond 8 the ISP may only bond 4 if you are not paying for a higher speed tier. However the price difference between the two is small enough that I think springing for the 6141 is probably a good idea in general. So yeah, your right.

If it's a recommended modem, its more than likely they support that many channels. It's in the ISP's best interest to support as many channels as they can with current infrastructure to save them money. With DOCSIS 3.0/256QAM modulation they can push ~42.8Mbps per channel, but if everyone is using the same channel(s), no one is ever going to get that kind of speed.

I'm looking for something to replace my Asus WL-520GU and am currently looking at the ASUS RT-N66U.

I just want something that I can use to setup a VPN connection for a specific device on my network to watch American Netflix on my TV (but not affect the other devices on the network). I can do that now on my WL-520GU with Tomato but it doesn't really have enough RAM to do it and I need to restart it every day.

Is the RT-N66U overkill for that? Is there a cheaper router I can get to accomplish this?

Right now the RT-N66U is $139.97 at one Canadian store: http://www.ncix.com/detail/asus-rt-n66u-dual-band-wireless-f6-68505.htm

If you have any alternatives that are available at that place or maybe BestBuy.ca, I'd appreciate it.

Thanks

VPN clients on Asus devices (and most home routers) are for the whole network, and not one specific device. They're also grossly under-powered to do tunneling like that at decent speeds, with a PPPoE connection I'm lucky to get 10-15Mbps on my 25Mbps connection.

HOWEVER there is another option (this is what I do), if you use a geo-DNS server like Unotelly/Unblock.us/etc, you can install asuswrt-merlin (fork of the official Asus firmware), and have certain domains resolve with a specific DNS server using dnsmasq. No overhead of encryption/decryption (FULL connection speed), only Netflix would be modified (all devices would have [insert region] Netflix, though, if that is a concern), no VPN required.

Does the Netgear Powerline 1200 pass muster?

It's all well and good to look at benchmarks, but powerline adapters are pretty much a "buy and see how it works in your specific house" type hardware. Different wiring, outlets being on different phases, appliances putting noise in the line, etc, will all impact your performance.

That said I've been very happy with my TPLink 1Gbps set. It's not as good as a dedicated cat6 (obviously) but they sync at around 800Mbps in my house, and don't add any discernible latency.

House wiring/extension cords aren't shielded so if you have a long run/coiled cord/etc you'll start getting EMI, it'll still work but you'll run the risk of lowering your sync rate.

I don't suppose anyone in here is familiar with carrier level fiber-to-the-home stuff, specifically Calix? I have an 854G-1 router from my ISP and when I call them they simply can't enable bridge mode on it. They say they're looking all through the config and they don't see it as an option, then eventually come back and say "yeah i guess it's just not possible on these".

But what's funny is that *I* can turn on bridge mode no problem, through the support login which I was able to find after some googling. When I log in as the support user I get a whole other menu of poo poo that I'm sure was not intended for end users. Anyway I can go into service WAN VLANs and change the service type from routed to bridged, and select which ethernet ports I want on the bridge. It works great.... until I reboot, then everything in that menu gets reset. I assume because it's downloading those settings at each boot (the normal settings like dhcp and port forwarding crap do stay between reboots).

I'm sure it's possible for them to change it, they either just don't have it setup for the support guys to be able to do it (although they can do it on all of their cable modems and other fiber gear, just not the Calix stuff) or the support guys simply don't know where to look. They're really candid with me so I if told them where to find it they would probably try for me. But documentation is pretty scarce.

It's a long shot I know, but maybe someone here works for a provider that runs calix?

I've never used Calix gear, but it sounds like you're only changing running config and not saving the changes to the config file

Generally this is done with a command like "nvram commit" on a lot of devices, poke around for something like that in the calix device. It's likely not exposed on the web interface and you'll have to telnet/ssh in to the device and issue the command.

eg: My desktop both has an internal IPv4 from my router that it got from DHCP, and a public IPv6 address that it got delegated with DHCPv6-PD.
