GT-AC5300 low signal strength on 5G-1 network

    I picked up a GT-AC5300 several weeks ago, as an upgrade for my failing AC-87U, and have been pretty happy with it. I am having a problem though, where the 5G-1 has low signal strength. This is an issue regardless what wifi channel is used. The 5G-2 network doesn't have this problem.

    An example of this is that standing within a couple meters of the router will show 2 out of 4 for signal strength on a MacBook Pro, iPad and iPhone. It drops to 1 out of 4 pretty quickly.

    You can see my wireless settings here:

    Any suggestions would be greatly appreciated.

    My all 3 of my RT-AC5300 have less strength on the 5G-1 as well, not to the extent you mention though, you only notice when a couple of rooms away. I assumed it is how they all are.
    Maybe yours has a fault which accentuates this ‘feature’.

    Seems like a classic bug. If you don't get this resolved, you may want to get a Linksys EA9500v2. Its more or less the same hardware as the GT-AC5300 but without the bugs :)

    You may want to install a wireless survey software, highly recommended WiFiAnalyzer for Android or inSSIDer for ios, and post the the measured values for both 5GHz bands. I wouldn't rely at all on indicators on devices.
    There will be a significant difference (8-9db) if the second 5GHz radio uses a channel >100+.
    In US:
    36, 40, 44, 48 200mw
    52, 56, 60, 64 1w
    149, 153, 157, 161 4w
    In Europe
    36-64 200mw
    100-140 1w
    155, 159, 163, 167, 172 4w
    So based on the chanell you're using, you will find a decent difference.
    I'm like 2m away from my router, and 1st 5GHz radio gives me -50 on channel 52, while 2nd radio gives me -41 on channel 100. I'm in Europe.

    36-64 @200mW and [email protected] are ok for EU.
    But where did you find anything about 155-172 @4W?
    Never heard about that in EU, only GB allows allmost all channels possible.

    No, I just copy pasted wrongly!
    Those channels are for BRAN, not wifi for home.

    So, we should just ignore what you posted?

    Not quite: 100+ are significantly stronger in Europe
