WNR3500U/L/V2 - Tomato 1.28 - Speed issues

Post by nymnom » Thu Aug 13, 2015 5:51 pm

Hi,

I'm finding a huge loss of speed when my VPN is run from my (new)router as opposed to from my laptop, and as I now want my entire home network passing through the VPN that is really quite annoying. My router has been set up as per this guide - viewtopic.php?t=6097

Peak speeds measured by speedof.me using closest node -
No VPN/IP Tables (Router) ~26Mbps
VPN +/- IP tables ~5mbps!!!
VPN (Mint Connection Manager)~18Mpbs

After reading a post on my service provider's message board I've tried changing my MTU setting to 1400 on both my router and within Mint Connection Manager, to no noticeable difference. Nothing in the logs helps me... Beyond that I've fiddled, read some more, pondered and swore - all at length, but to no avail.

Basically I could use some tips on even where to start, please. I've been a superficial linux user for some time now, but the intricacies of networking and encryption are seemingly beyond me, and I am new to Tomato....

....as being the only human being in the household to care about not revealing every-damn-thing we do on the internet to the government, or at least who wants to make it awkward for them, this is not helping my cause! All the rest of them want do is stream completely pointless shit in very high def all at the same damn time. :wtf:

Cheers.

Edit
Running the 'top' command via SSH while running a speed test reveals the openvpn stuff using ~70% of the CPU. Could this be the problem?

nymnom,

Indeed your router CPU will be the bottleneck. Encryption and decryption are fairly demanding.
This is a typical observation when running openvpn on a router.

Bugger. Thanks for the confirmation, Fermi. I suppose there's nothing to be done other than some thorough research on it's replacement then.

/\ Oops.

In conclusion, the solution to my Netgear woes in a family usage context was to buy the Asus RT-AC68U. Everything is better. To labour the point to those in a similar situation to mine; you really do get what you pay for...unfortunately.

Fuck you, GCHQ/NSA! You'll never know the vaguely left of centre newspaper articles I read, or what minecraft videos the kids are watching! :twisted:

This may bring some "divergence" in ideas but I've installed my share of routers (https://mirciado.com/wp/?product=tealcs-cs-router) with OpenVPN for CS only, and I found out that:

1) CPU of the router is the big bottleneck, so get a faster router :-D, OR JUST

2) use OpenWRT CHAOS CALMER (15.05 RC3) gives almost identical speeds as a laptop running OpenVPN, but you can't install LUCI, has it needs all the available memory it can, I'm running mine with TP-LINK TL-WDR36000 connected to CS and it's almost as fast as in the laptop.

3) If you only want Tomato, there are a lot a forks from the original but the best one is without a doubt http://tomato.groov.pl/ :-)

This is my "2 cents" on this router/openvpn/CS VPN stuff, I have to say that like you, I'm protected for 1 year now, and my router automatically cycles connection every day :-) or when it reaches a premeditated number of incoming connections, it also flushes internal DHCP's (yeah I know I'm paranoid lol)

I think Chelsea and Ed made clear that it ain't just paranoia!

Tealc, thanks for the info. With being such a newb in this regard all is helpful. I'll play with OpenWRT on the retired little black box - I'll not be able to encourage those in my peer group to give this stuff a go if it's solely based on how much money needs to be spanked in order to make it transparent, functional and less faffy for a family. I'll also read into/play with Luci, so far I've not touched it.

Having said that, I have no shame in buying the new router. It has 3 antennae and looks a bit like it's made of carbon fiber; all very important aspects to the little boy within :D
