<p dir="ltr">How hot is it when it goes into stupid mode? Also, is there anyway you can setup to get voltage and current data between power brick and unit. Lastly, when was the last time you reinstalled from scratch with all new passwords just in case it's been compromised.</p>
<p dir="ltr">Oh. Are your speed tests to other machines at home (wireless to wireless and wireless to wired) all by ip only?</p>

I'm looking for some brainstoming ideas to explain why my home wifi
router's performance is suddenly acting so strange: periodically
(about once a day), performance (as tested by <a href="http://speedtest.net" target="_blank">speedtest.net</a>)
drastically decreases from ~30Mb/s to ~4Mb/s.<br>
<br>
When this happens, there's nothing I can do to make it better.
Rebooting the router has no effect. The speed comes back when its
good and ready - not before. These "outages" usually last about 12
hours. Performance is bad from all clients - macbook, ubuntu
laptop, phones - so this seems to be router specific - not due to
client config.<br>
<br>
NOTE: tests via 10baseT wired connections are consistently at
29+Mb/s; wifi is 26-29 when good, when bad between 0.9 and 4Mb/s.
When the wifi is bad, the wired results remain good: so this is a
wifi problem - can't blame it on comcast :) <br>
<br>
The router is an Asus RT-N16 running Tomato/Shibby. Google shows
others getting much better throughput with this hardware/firmware
combo (70+Mb/s) so I don't think the router or firmware is likely to
blame (unless I have flakey hardware ?)<br>
<br>
I've been logging through a speedtest-cli cronjob for the past week
and 6 days out of 7, I see this behavior (performance degrades
starting between 9pm and 2am, continues even after the router
auto-reboots at 5am and then eventually returns to normal by about
9am. <br>
<br>
Things I've tried:<br>
<ul>
<li>I cannot identify any equipment in the house that might be
causing radio interference - and certainly nothing that is on a
periodic schedule that matches these overnight outages. </li>
<li>Reboot the router - has no effect.</li>
<li>Checked that this is not client specific. When the performance
degrades, I measure the same throughput on all clients (laptops,
phones).<br>
</li>
<li>There is no load on the wifi during these outages (no long
running file transfers, backup rsync's or streaming).<br>
</li>
<li>I disabled bandwidth and ip monitoring (which I understand to
be a known bottleneck in Tomato). This improved the "normal"
throughput a bit, but has not solved the periodic slow
"outages".<br>
</li>
<li>I moved the router to a variety of locations (on theory that
there may be some unusual interference on one location or the
other)</li>
</ul>
<br>
I'm looking for ideas of more things to try before I reflash the
original firmware and see if Asus's software works better...
(followed by trash the asus and buy a new router :( ).<br>
<br>
Help! (and thanks,)<br>
