Hi, guys!

I apologize if this has been already discussed but I tried to seach the forum and couldn't find the answer.

Here is my problem:
I bought a brand new Linksys E3200. Followed exact instruction and flashed the unit with the initial mini build and then with mega build. Logged in, changed the settings to my requirements and everything perfectly works. However after a random period of time, the wireless network still shows on my devices (iphone, ipad or HP laptop) but it is "Unable to join". I have to do hard reset 30/30/30 to get it to work. I even could not login thru wired LAN connection.

I reverted (as per the instruction) to original factory linksys firmware. It works without any issues, then loadedDD-WRT firmware again per instructions (to the point). Manually inputed all the settings again (nothing special, just setting WAN IP to static, DHCP for clients, Wireless just changed SSID and set WPA2 Personal security and set QoS). Again everything works perfectly bu after a random period of time the same issue.

Can you please help on figure out what is wrong? Is there some log file somewhere that could tell my why this is happening?

Thanks a lot and I apologize if this was already discussed.

Could be overheating.

Mine becomes unresponsive and requires a reboot if I download at 20Mbps+ WAN-WLAN and have a few other clients connected and doing some stuff. CPU load hovers around 0.6-0.8 at that point before it becomes unresponsive and requires a reboot.

Btw rebooting is just a temp solution, have to slow down the downloads or it happens again, or switch to wired.

I somewhat fixed it by putting two erasers on the bottom of E3200 to elevate it by about 1 inch. I also lowered the transmit power of the wifi, which combined seemed to lower the overall temperature of the router (by touching the bottom/top of the router) and it hasn't dropped connection/required reboot since.

However I can still cause it to become unresponsive/overheat/require reboot if I download at 30Mbps+ WAN-WLAN over 5Ghz wifi (loading Tomato on it of course, since DDWRT doesn't support the 5Ghz radio on the E3200). But I usually do my high speed transfers over wired anyways so not a problem other than for stress-testing purposes.

Thanks a lot. I will try that overheating solutions. However, this must be something else. I think it is very high P2P traffic from my buddy living with me. I searched the forum and learned about some table that gets filled in pretty fast.

I do not think overheating is the issue, router works if that P2P is not running, but when he has it running it becomes unresponsive after 10-20 minutes.

I changed TCP and UDP timeout to 120. Changed max amount of ports to 4096 in IP Filter settings. Set his Mac address to bulk and still it is not improving.

I do not know what to do. I'm lost. If at least I can pull out some log why it becomes unresponsive, it would help to change some settings.

you didnt specify which build you are running. earlier builds suffered qos problems, but later builds qos works good.

you can try a later build and setting some speed limits for his mac address to see if that helps.

Hello.

I flashed the E3200 with this file:
dd-wrt.v24-21061_NEWD-2_K2.6_mega-nv60k.bin
and it says:
DD-WRT v24-sp2 (03/25/13) mega - build 21061

I setup QoS and his mac address to BULK and as I said in my very first post, I do not have issues with my internet speed over wireless or wlan at all when modem is up and running.

However, for some unknown reason ( i think it is P2P overload) it stops responding after a random period of time. I mean sometime it takes 10-20 mins, sometimes 3-4 hours. Last night it was working for about 15 hours.

And I'm clueless why.

[smokinabowl]

qos should work fine in that build.

setting priority to bulk just means that his mac address will be put last in line, but if there is no other activity he will still receive good service.

what you really need is per user bandwidth limiting, do you have that option in your qos? i dont on the 20675 build but there is a help note on the right hand side about it, maybe it was added later in your build?

Malitiacurt had some good info with the overheading/overloading of the unit, bandwidth throttling would help that, as well keeping it ventilated better.

there is also a thread out there about the cheap underpowered power supply bricks being shipped out with later linksys and other units, its possible your power supply is weak and could be causing you issues under heavy load

I found the latest build and updated to it just to see if it makes any difference, however there is a glitch. When setting up Static IP for WAN the save button and apply button does not work.

[lostfx]

The per user limitation. How do I set it up? I found that there is a premium paid version for that functionality. I have no problem buying it, but I do not know which one should I buy for my router.

[Murrkf]

Paid version not available for k26 builds. K24 only.

[lostfx]

So what are my choices? Is there any other way to do it? I think there is a way to set it up thru SSL, but whatever I do I cannot establish SSH connection to router only Telnet.

[Murrkf]

SSH was broken in some recent builds.

I'm having exactly the same symptoms on my Linksys E1000 (a thread open here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=171311). Easiest to get it to crash is if I use AirPlay between my Mac and my AppleTV, if I transfer large files on LAN or Wifi or sometimes when downloading big files.

Can you recreate the problem/get it to crash if you transfer larger files over LAN on Wifi as well?

I'm seriously thinking about giving up on it since this limits my network usage too much
