    I have been trying different approach towards if what I am reading on my rssi and signal quality are accurate. My notebook shows rssi of -75 and quality 15 but on the notebook shows very good or good this is an intel 5100 agn and wireless from my 5 ghz. Distance away from router 8 or 10 meters with 2 walls I could move around to different spot and get excellent signal reading 100% but the device list would show -50 rssi quality 20 or 29. My xbox 360 S is within 7 meters direct line of sight has those a high - 40 or -50 rssi and 30 or more not even breaking green quality some disconnects. Currently using shibby 114 on my linksys e3200. I was using the AdvancedTomato version it did the same with device list information. Things I have done using the Floor Noise on both eth1 and 2 gave me 90 and 92 also tried different setting in the advanced wireless section was tried lowering power nothing changed inputting a higher power range would increase the problem, interference from other devices practically none I would have problems with other wireless modes i had been using. Tried all interference mitigation no affect anything else most likely would not have worked. I live in Texas and us is selected under country of course. I read a post dated a couple of years back stating same events with rssi and quality, one of the things was try using a different country since the driver was in some kind of powerlimit due to country selection, I felt that if that is the case then it may only be just misleading me and just continue testing, bandwidth, ping testing. I peronaly never saw this before i alway used the other wireless modes with great successful using client mode or ethernet bridge but now using access point that now the device list comes to my attention on my network and now that is the only difference I am using tomato for now than the other methods of use. Everything works just fine with testing done from notebook on both 2.4 and 5 ghz both have excellent throughput up and down are excellent. The device listing is just misinterpret my network devices rissi and signal quality. My router is just connected from the fios router switch port 1 to my routers wan port different subnets, fios wireless disabled, firewall set to minimal. A configuration like this would not cause this type of information on a seperate device, subnet. I suppose the driver changes with modes that are used and may have added or lost a few lines of code for device list information would there be something in the wl cmd to fix this?

    Updating information, I have not had any problems with my bandwidth but the "device list" still shows my wireless clients to almost being disconnected with terrible interference or signal, but when running testing ul and dl are excellent evening my ps3 playing black ops, hulu, netflix or my xbox playing netflix any other app or playing black ops are at optimal performance wireless with no disconnects or buffering. From the last post to the now my router has been outstanding along with the ethernet connections are also at optimal performance, qos works wonderfully this seems to be the only real problem(device list) that I have run into since using tomato firmware for my linksys e3200. Now if someone was to come over with their own device and having connection problems I wouldn't be able to rely on the device list for help in determining the problem I would assume it maybe on their adapter settings since my network is fine both hardwired and wifi. I would hope that a developer might give me an ideal what to adjust, I had already done 30-30-30 in first stage then went to "configuration" erase all data in nvram memory throughly twice pulled the power for 30 seconds let it power up get to the gui then 30-30-30 before using to where I am with it today with no affect to how it displays information. I suppose I could deal with that if I have to.

    The data in the device list seems reliable for some specific combinations of firmware and router, but not others. It would probably be very difficult and time consuming to fix, and other features would likely break in the process. It's a known issue.

    As long as it being documented and posted maybe it will be addressed in upcoming updates only time will tell.

    I have read and reread this but I'm not sure I understand exactly what your problem is! The RSSI indicator is a field strength test, if one of your clients reads low, but still works, that is probably quite normal. I can get pretty fast throughput with -75 RSSI on a clear channel.

    How exactly did you interpret this data?

    That was only just reading the information from the device list, in which it really has it backwards rssi has readings for my signal quality with signal quality reads rssi. For a week nothing my wireless network is pretty stable, solid for short and long distance, I've tuned down the power to only travel at least 20 or so meters. When I wrote the statement you have there is that device list shows what would appear to be some bad interference or terrible signal quality but reality it works fine just the readings on the device list seem to indicate reverse order.

    Later this evening I'll install your build toastman to see if my linksys will give me same results. I know in performance it worked wonderful but I didn't use it wireless mode: access point, I used your build and shibby's build for wireless client or wireless ethernet they performed excellent in my case. So you see there was no need to even look at the device list, til now I see again no performance issues just the random thing that goes on with device list readings. I guess if you were to look at it you'd probably start troubleshooting or just telling the forum that there is a problem with my wireless connection to clients rssi and signal quality. I did my tests with simple internet speed test, then ping tests, local and internet. Bandwidth test done on internet and local files also used testmy.net for different size file for download and upload through wireless connection. I hope that gives you an ideal that device list just gives you a reveres reading that may look horrible and what i did to determine that the wireless network is working perfectly normal.

    RT-N16-Status-RSSI.PNG

    This is the display from an RT-N16. I don't have a 3200 but it should look like this. I can't imagine that these can get reversed, unless somebody deliberately changed the code to do it, which is unlikely! Strange.

    I wouldn't imagine the code to be changed, strange it would on my router model? However maybe fluke in installing for my linksys e3200? I posted these images the xbox should be also eth1 but it shows bro, it had been configured for static, with port forwarding since I have a double nat and it wasn't connected or on at the time of this photo. The elite is the only notebook that we use in its location is within 8 meters away through two walls, when it sits in iddle the connection normally drop to 72 mbps til being used. I get that information from the notebook status then I would check by running a few tests that I explained on earlier post my method. I'd like to know if I get the same results from your build for the e3200 but to let you know I am happy with tomato firmware something like this is workable if you know everything works to your needs and with some experience and reading forums you can troubleshoot and determine logical outcome. I know you use the fileshare site I will use the link posted here and will report back sometime today, right now I am sleepy it turned daylight savings.

    Have a good day.

    That RSSI and "quality" look normal. The numbers on the connection speed do not always reflect reality in all router - firmware combos, but in your case look reasonable. Those numbers go down when the device is idle (to maybe 6/6) and up when the device is active. There will usually be a difference between the sending and receiving rate when the connection is active.

    I have to disagree on the first part as I mentioned in previous post on this thread that the rssi and quality are in reverse order as far as information on wireless client goes. I do not have any connection problems and I am well aware of how wireless connections goes into some power save til it may become active then the connection reestablishes to the router. What you see in my images would most likely have connection problems with latency, maybe disconnects and ping issues slow response time. My tests gave me what I would have had if I were connected to my lan port give or take a few in ping but you get what I am saying. I live about 50 miles from dallas tx and with 9 ms maybe 2 or 0 on latency, then I would in around the US 50ms ping and latency 4ms to 9ms from east coast to west coast in the United States some states in between may give me at the most 80ms ping. I hope you understand this not about some reality with firmware router combo, it is about how the information is backwards when the image was taken my notebooks connection was in idle when I prepared it to uploaded to linksysinfo site from my PC-777 that is connected to the router in the other room but if you were to switch the rssi number to the quality number and the quality number to my rssi number then that is what should be there. Does that make sense?

    I guess I don't understand:
    90-59=31. The numbers are as expected for a very high signal strength (59 is very good) and minimal noise (31 should be plenty for 802.11n at full speed). I get low ping and high throughput with "quality" in the low 20s. Toastman's screenshot was probably with a client and router right next to each other.

    Ok now if you place what is indicated from toastman's rssi to -83 instead of -36 and the quality from -36 to -83 that is what my device list is telling a reverse information and if you were to read in that perspective then most likely problems with wifi interference. The floor noise is fine even if I was click it, it stays around those levels -90 or -92. As I have said in this thread nothing is wrong with my router or settings. Just that the device list has my readings backwards so to speak. Remember having a rssi over 40 is a problem.

    Please post your screenshot again as none of us can see the reversal of which you speak in the one you posted already, it is perfectly normal.

    At the time the device list image was taken I was using my notebook it is there elite1. I edited the image then I left it there for maybe a few minutes basically idle time. RSSI -59 dbm and the Quality -31 dbm is what you see I am also awhere of the numbers. 90 - 59=31
    Now I already now that the wifi connection runs perfectly. So I come to the conclusion that it maybe it reverse but I guess I shouldn't put it that way but the quality goes lower to - 20 and rssi raises - 80 or more when in heavy use. The readings from my jpeg indicate a bad connection with interference. Think about it if my rssi was like that I would have some connection problems for my notebook and my consoles that are within 15 meters or less and it would be whole different topic. Ok not to change the subject your firmware size shows 7.2 mb is that normal? I remember that it was like 9.4 mb. I ask you since I downloaded the firmware and strange enough i received dosearch.com virus and this why I ask the file size is correct before I upgrade the firmware. I since then got rid of the malware virus.

    Thank you for your time it is just that this is what is presented to me on my router. I can deal with it, I know there is nothing wrong with my router and its configurations.

    The numbers are not reversed, but if your RSSI is dropping to -80 then there may be an issue. You would not get maximum throughput at that level, though you would probably not drop the connection since you have so little noise (I'm a bit jealous of the low noise).

    7.2MB sounds about right.

    I have installed the tomato-E3200USB-NVRAM....SR2Toastman-RT-N-Ext.bin. Before the install the 30-30-30, erased the nvram, upgrade with check into after flashing erase data in nvram memory, when done erased again pulled power for 30 seconds, login and began configurations for lan to lan connection, disabled dhcp, ip static, wireless setup to original as usual to my network, wpa2 personal, aes did a scan 11 was fine. Checked the Noise Floor still fine what was determined there by router. Advanced wireless I only made a change into the 80211n preable to GF-BRCM call my crazy but works better for me, pwr level doesn't really seem noticed but I just usually 42mw zero seems high on mw for default, the country United States. WMM is set to enable, I noticed that if you place auto it will switch to enabled but it does effect the wireless connection then settles to a normal state. Disabling it would not really do anything if you want to achieve a good N connection or any good connection so I never disabled it. Oh and why no 5 ghz? I did a few online tests from my notebook.

    The image3 is just in use while I ran a speed test, with image4 being the result. Next is a speed test from speedtest.net it gives different results probably because two different sites do different methods of testing. Testmy.net uses your browsers with java and speedtest.net use adobe flash. image5 just shows and idle. image6 and 7 show after then on 7 i placed my cursor over it shows signal performance. The remaining images are just idle. I was under the impression that rssi from -0 to 40 it relatively excellent and quality would be in a higher number range. I suppose the it is from the routers perspective this is how it sees my notebook and my notebook see the router better. I guess this is how the firmware works for my hardware/model.
