Opal (GL-SFT1200) - Terrible 2.4ghz performance in Repeater MOde

Hi all,
i’m on latest 4.3.7 firmware.
If i join network with my PC my first home router i have 20Mbs performance. If i join the network with Opal i got 2-3Mbs, placed on same desk of my notebook.
What it seem strange is the unknow data here:

wlan-sta0 ESSID: “censored”
Access Point: censored
Mode: Client Channel: 11 (2.462 GHz)
Tx-Power: 0 dBm Link Quality: 34/70
Signal: -75 dBm Noise: unknown
Bit Rate: unknown
Encryption: WPA2 PSK (CCMP)
Type: nl80211 HW Mode(s): 802.11bgn
Hardware: unknown [Generic MAC80211]
TX power offset: unknown
Frequency offset: unknown
Supports VAPs: yes PHY name: phy0

i tried to revert to old firmware and hard reset but no luck
any idea? i also tried to disable 2.4ghz networks on the router itself

the wireless page on luci it shows No data for TX/RX Rate… this is another strange behavoir based on my experience with other gl.inet products

20 Mbps isn’t great with your laptop either. What kind of access point is this? What’s your internet speed rated for?

If you have an Android phone, I would recommend downloading and installing an app called WiFi Analyzer. There is a free version with ads (pretty obnoxious ads), and an Open Source version with no ads (search WiFi Analyzer Open Source) on the Play Store.

If you have a lot of interference from other WiFi systems nearby, I have found the performance to be worse than my laptop by a large margin. You may have to change frequencies and change the bandwidth to 20 MHz.

Hey Bro,
Thank you for your answer.
I already scanned my area and there is no much interference. Already set up 20mhz.
Anyway, the strange behavoir is:
First no data for TX/RX (see screenshot)
Second: why my notebook is so much faster? Which parameter can cause this difference?

My line is 100mb but router is a little bit far by my upstair.

Mine also says 0 Bbps even when it is working. This is a software flaw.

I don’t think you will get it to work with that signal strength. At least yours is measuring the noise. Mine doesn’t even do that. You’ve only got a signal to noise ratio of 11 dBm. You need to get it up to about 30. This WWAN radio can’t handle what you’ve got for a signal. The Opal needs a very strong signal to work properly, stronger than any other device I have used. Also I have found the Opal works better with some access points vs. others, even at the same signal strenght.
