My Adventures With DD-WRT

Over the past few weeks I been planning to redo my network. Goals include replacing aging hardware, simplifying the network, and reducing PC I use as firewalls with appliances.
 
One of the things I am taking a look at is converting a cheap router into a powerful one. I have several that dd-wrt supports, but a recent sale at Fry's for the same model I have sealed the deal. Because I am familiar with it and it was reasonably priced.
 
The router is the Cisco Linksys WRT310N.
 
These series of article documents how I configured the router and my adventures with it.
 
This would fit a blog format, but I already have a blog and would rather try something new and different. So I am puttying these documents in a drupal book instead.
 

Default Internal Device Network

Initial Install

Here we will make sure the unit is working and the device is up to the latest firmware.

The Router

I have worked with several routers over the past few weeks and was in the middle of deciding what I wanted to use, and yesterday there was a sale for a router on 1saleaday that was cheap enough to play with. But I procrastinated and missed the sale.

FrysWRT310NSale

 

But that is a good thing because I came accross a sale in the December 2nd 2011 Fry's Ad for a Linksys WRT310N router.

I actually already own the 610N, so I have experience with it and the price was reasonable.

If this was a Mail In Rebate Deal I probably would not have purchased it, but it was 39.99 + 3.80 tax out the door.

So I grabbed another "customer" and we went to Fry's and purchased two of these routers for my experimentaion.

So now I have 3 which when I am done messing with, and experimenting, will go into production.  I am still unsure what the final network topology would be but at this price I am willing to give it a try.

 

My Experiance

I did not purchase my first router 610N, it was actually given to me by my sister because it had so much issues.   She did call Linksys Tech support and they were going to charge her quite a bit to reflash her router.  If I recall it was about $100, which from a labor perspective is right (I think it was out of warranty), but from a financial perspective it did not make sense.

So she asked me to take a look at it, from the get go it did crash a lot.  It sat around for a while at my place after my sister decided to buy a another model.

My colleague A.J. helped me flash this router.  He noted that this was Version 1 of the hardware and he had version 2, both seemed to have stability issues.  But seemed to come down to heat, he drilled some vent holes in his and that resolved his issues.

I did not drill any holes in mine, but I did have some stable uptime for months, until an update last week, the uptime on this router was over 100 days.

That works for me, I seem to reboot my comcast router more often.

The General Specifications

I am going into a lot more detail later on these particular models.  But here are the specs from the box.

These are WRT310N Cisco Linksys Routers

  • It has a single 2.4GHz antenna,
  • Four Gig Ethernet Ports
  • A Single WAN Port

Not much info.

WRT310N Unboxed

I was excited for having a toy to play with and some time in the lab to test it out.

The box that the router was shipped in was certainly not exciting.

The contents were as expected, an Installation CD, Power Adapter, Network Cable and the Unit itself.

I tossed out the other stuff, don't need it.  Linksys was nice enough to protect the case of the router.

Its hard to read but there is a label covering the ethernet ports in the back. It instructs the user to install the CD first. I personally find these labels hilarious.  Ripping it out, don't need it, heck what I am doing will void the warranty anyway.

Here is the bottom of the unit, if heat becomes an issue I am raising this up, if it is still an issue, I am placing a fan under their to force air up, if it is still an issue, I will drill holes in the casing on top, if it is still an issue, I will attach a passive heat sink (no fan) on the hot components, finally if it is still an issue, I will put an active heat sink on it.

And the most important thing to me, finding out if this is a v1 or v2 of the WRT210N model, its a V2.
No time to set it up.
