Networking Issue - Hardware Or Tomato Settings Related?

    I am running a Linksys E2500 v1 Router with the latest version of Advanced Tomato installed on it. Once I have 4-5 devices connected on the 5GHz channel of the router, I am often not able to add any more wireless device connections to the router. Even by disconnecting some of the existing connected wifi devices, it doesn't seem to allow any new device connections once it locks out a particular device. Only after a reboot of the router can I connect the other devices that wouldn't connect previously.

    I don't think the router has been set with a limit in Tomato on the number of wireless device connections. So not sure what may be causing this problem. And at the moment I happen to have 6 wireless devices successfully connected to the router on 5GHz and all are running and accessing the internet without any difficulty.

    So the problem seems to be intermittent. But I tried to add a 7th wireless device connection just now, an older iPhone that runs only on the 2.4GHz band, and it won't connect to this device even though there are no other devices connected at all to the 2.4GHz channel at the moment. The other 6 connected devices are all running on the 5GHz channel.

    It basically seems there is some sort of connection problem once I have 4-6 devices connected.

    Are there perhaps any settings in the Tomato firmware I may have forgot to make, or that I should change, which would improve connection stability?

    you might check advanced, dhcp / dns server, max active dhcp leases and advanced, wireless, max clients ( per adapter )

    Thanks. Max Active DHCP Leases is set to 255. Maximum Clients is set to 128 per adapter, total of 256. So I changed the Max Active DHCP Leases to 256 so that is now at least equal to the total amount of the two adapters combined. I never have more than 7-8 devices connected at any one time, so the change probably wont make any difference, but let's see.

    Thanks for the help. I have heard v1 routers have more problems than v3 routers on this model, but not sure if that is correct.

    Can you share you settings in advanced wireless?

    Yes I can. Which settings would you like to know about? There are close to 30 settings in total for each channel.

    in standard tomato, under basic, lan... that is where you find the DHCP scope.
    here is a copy of what I have
    Bridge STP IP Address Netmask DHCP IP Range (first/last) Lease Time (mins)
    br0 Disabled Enabled - 61 1440

    I have hmm, lets see... at least 4 cell phones, 6 tablets, 2 laptops, a wii, ps4, a roku, and a chromecast (there might be some wireless adapters in desktops that I am forgetting) and never had a problem with not enough wireless connections (currently netgear R7000). I did have a dlink dir-669? (I cant remember the exact model) a few years ago that did seem to have a limit. It may be hardware related and not firmware.

    Thank you Sortec. Yes, it does sound more like hardware than software perhaps. I may look for a second hand v3 of this router since they are quite cheap. I have the oldest v1 and I think it may have some intermittent hardware issues at times as I have heard other people suggest.

    @Sortec - By the way, I am running version: 1.28.0000 MIPSR2-3.4-140 K26 USB Max and I don't have just DHCP settings under Basic - Lan. Under Basic I have DHCP/ARP & Bandwidth Monitoring and under the Advanced menu I have DHCP / DNS Server (LAN) settings. Below are screen shots of both setting scopes and they don't seem to correspond at all to any of your settings I am afraid. Thanks.

    I think what we are seeing are some of the differences in layout of advanced tomato compared to regular tomato.

    I use regular tomato written by shibby. current version is 140.

    Ah, I see, thanks. I tried Shibby. I couldn't get any devices to connect to my router or my router to connect to the internet with Shibby so I gave up and went back to Advanced Tomato. And as the name suggests, Advanced Tomato has a much more advanced looking layout. I know a lot of people use Shibby, but it didn't seem to work with my hardware or network connections.

    That is the only difference. He takes shibby's code and puts a gui on it.

    It seems there might be a bit more different about it because, as I said, I couldn't get Shibby to run any services at all on my router.

    When you change firmwares like that you have to fully wipe NVRAM and set everything up by hand through the website, you can't restore a config. It sounds a lot like either you used the wrong firmware for an E2500 v1 or didn't wipe the firmware. Some routers have a special build just for their model. Sometimes

    Shibby doesn't build for every model every time, so you may want to poke around in older firmwares (start at 132) and see if it's there, then roll forward looking for another firmware with the same name.

    TBH I'm not running any Shibby firmwares after 132 - keep looking, keep having issues, keep rolling back...

    Thank you. I was not actually wanting to install Shibby on my router. I was just commenting that it didn't work on my model very well when I had installed it. Yes, I did all the wiping of the NVRAM, etc when I tried to get it to work. Advanced Tomato works great though. No problems, other than some possible hardware issues with my router as I have been discussing in this thread. I may end up switching to another router eventually.

    I was just looking at some of my settings and I realized under Basic Settings-Network-LAN I had my IP Range (first/last) set from to I have now bumped 105 up to 112. But would a range of only 100 to 105 have been limiting my number of wireless connections to only 6?

    no, the number of connections is determined in the advanced wireless panel, number of clients for that radio.
    but dnsmasq will not issue any ip address leases anymore, so the connected client cannot communicate.
