Cisco Linksys E3200 missing 5GHz wireless

    Am I correct in assuming that the reason I don't have access to the 5GHz bandwidth on my E3200 is because the processor is an R1 and not an R2? If so, could someone tell me why R1 can't have 5GHz wireless enabled?

    Thank you!

    Are you referring to radio, or bandwidth? Read this it may clear up some of your questions, http://www.linksysinfo.org/index.php?threads/tomato-modifications.26037/

    Only the 2.4GHz radio is shown. The 5GHz radio isn't listed anywhere. Could you point me to the need in the haystack you referred me to? Because, I only see that the 5GHz radio wasn't working back in 2012. Are you saying five years later and it still doesn't work?

    dual band has been working since back then only tomato and oem have working dual band for the linksys E3200 and the link is suppose to clear up the meaning and symbols R1, R2 that information is there. What firmware are you using now tomato(shibby/toastman)or dd-wrt? Toastman has an earlier version without 5ghz and dd-wrt doesn't support it.

    I have the same router and gave up with 5ghz. Radio worked for a short period of time then it disappear or speed was ridiculous. Most of the times a reboot worked the issue but it wasn't worth it, I finally turn it off from GUI and never enable it. 2.4 in the other hand works ok.

    I still use my E3200 as a wap these days but as far as it's been using tomato about maybe 4 years, and I really never had any issues with it on both dual band, 2.4ghz setup on channel width is 20 and of course 5ghz is 40. Currently it has Tomato Firmware v1.28.0511 MIPSR2Toastman-RT-N K26 USB VPN installed. I have had different versions of tomato on it and dd-wrt, at one time I had openwrt on it(almostyear1/4ago) but at that time openwrt didn't have radio support for either one. Just saying that for my experience I may have gotten lucky with a rock solid little dual band router, and been able to experience such open source projects as tomato, dd-wrt and openwrt.

    Can you check and see if it has an R2 or R1 processor?

    If you noticed in the build that I have currently installed shows you MIPSR2, that the R2 is built that way maybe by sources and compilation to final build names, I can only say that how the developer may include dual band or not adding support to 5ghz radios on different reasons, one this particular for this router it uses a usb type firmware (broadcom) that works with the 5ghz radio and at one time dd-wrt didn't like how it was done so they decided to not include support the 5ghz radio for the linksys e3200. With OEM firmware developers don't include all their source code, so for open source developers they use mostly use binary in some cases will get a chance to use closed source, all these things are documented. If you are interested in knowing more feel free to google to hearts content.

    Well, my E3200 has an R1 processor. I think that's why I don't get the 5GHz radio.

    No it doesn't have a MIPSR1 processor!!

    You give so few details to narrow down the problem you are having, so my best guess is you are using a Shibby build after v132 (he added multi-wan to later builds) & are using more than around 32k of Nvram.

    Flash back to v132 and keep the nvram under 32k and the 5GHz Radio should work.

    A google search would have provided the answer too.

    The Tomato interface states my E3200 has an R1 processor. But, I'll look into v132.

    Sorry, I'm a Tomato newbie. Have been using DD-WRT for years. But, the 5GHz radio isn't supported by dd-wrt for this model.

    Normally flashing the wrong architecture results in a brick, but if it somehow managed to boot under an R1 build is not going to list the CPU as an R2 - all that firmware understands is R1 CPUs so it's going to show the CPU as an R1.

    I certainly don't see a single resource listing the E3200 with a MIPSR1 CPU. They all list it as having an R2 CPU.

    Actually, I found it I believe on the dd-wrt site of mentions of their being an R1 and R2. Doesn't matter at this point, I bricked it because I forgot to do the 30-30-30 reset before using the build pomidor1 posted. And I had flashed it with an R2 build in the first place and it reported itself as an R1.

    On dd-wrt they suggest doing a 30-30-30 reset for each time you change the firmware, but I've never did it and never bricked a router by not doing it. It would appear that isn't the case for Tomato. Oh well, luckily I only paid less than a dollar for the E3200 and don't feel like spending $30+ just to unbrick it.

    Sory, you say r1 just after that i thought to check it, can not get it into recovery mode set?

    Don't think the E3200 has a recovery mode, that's mostly an ASUS feature.

    I had originally put the R2 version of it on it. But, it reported itself as an Broadcom R1 in the Tomato interface.
