Slow VLAN

    I just loaded up Shibby Tomato for my Asus RT AC66u.

    I wanted to create a guest account so I made a VLAN.

    My only problem is the internet on 2.4ghz for guest is SLOW 1-2mb.

    If I connect the guest to 5.0 ghz then it is fast.

    Does anyone here know how to create a VLAN but still get fast speeds on 2.4ghz?

    What was the wireless throughput on 2.4GHz before you introduced the VLAN? Please disable the VLAN and test.

    Hi Marcel,

    Sorry, I'm new.

    Can you tell me how to find the throughput?

    I know how to disable the VLAN but where do I check for the throughput?

    Plug in a PC or Ethernet-based NAS to the router. Connect laptop to wireless. Copy a large file over network on your laptop. Watch copy speed (or watch task manager -> local area connection that is your wifi adapter). There's bunch of other ways too but that's a simple one that doesn't have too many external factors.

    Tomato also shows it under Bandwidth > Real time > WL(eth1) for 2.4GHz. But you have to make sure nothing else is connected to the router wirelessly on the 2.4GHz.

    Testing a 384MB file the throughput was 56.6 mb WITHOUT VLAN
    With VLAN it was 2.1 MB

    Your guests seem to be connecting at 802.11b speeds. Do you have any b devices? Could you post screenshots of your settings? (basic/VLAN/guest wifi)

    Edit: By the way, did you do NVRAM erase after switching to Tomato?

    I'm not home now but I do know that I set up the wifi to be mixed because I have devices for g and n. Will buy a new phone with ac soon :)

    Regarding NVRAM, this is a little tricky and I don't know if this has an effect. But I loaded up Tomato, not sure if I cleared the NVRAM. Then I spent about 3 hours doing all the custom configurations. Then I read to clear the NVRAM. DARN. :) So I basically backed up my config. Cleared out the NVRAM. Then restore back my config.

    Is this wrong? Wondering if the config file has something that might affect it.

    Unfortunately it is incorrect. You need to manually enter your settings after NVRAM erase. Restoring a backup restores everything, and you can get strange results after switching firmwares (or even different versions of the same firmware) if you don't clear NVRAM back to default.

    okay, I will find time to redo it all. Thanks Marcel.

    I will report back when I get it up.
