i have bt home hub 5 type A
I get a speed between 12-16 mbps while copying files from nas server over the wireless network
On the wired connection, I get 93 mb speed
Openwrt 19.07.03 software is installed on the device.
how can i solve this problem?
I only use LEDE 17.01.6 on VDSL2 fixed speed 55/10 mbps line, recording longest DSL uptime of 280 days earlier this year, with LEDE uptime recently passing 600 days. Others may be able to comment on OpenWrt 18 & 19.
If you are suffering DSL disconnections and local wiring in your property is not at fault (If you are in the UK, have you tested router at the Engineers Test Socket hidden within the BT master socket?), perhaps try a Broadcom based VDSL2 modem/router if you are connected to a Broadcom DSLAM. eg. TPlink TD-w9970 offers 'bridge modem' mode, to enable you to use a router of your choice.
The risk exists when flashing any router. The main issue with HH5A is if you do brick it, it can only be recovered using USB to serial-TTL interface.
What VDSL connection speeds do you get from your ISP? Is it a long line with broadband speed less than 30mbps ?
If you are having DSL disconnection problems with your original modem router, and with HH5A, I don't believe changing OpenWrt on HH5A will solve your problems.
As it is a general question about LuCI, and LuCI is a package, perhaps you may have to raise a new question in the appropriate sub forum? ("Community builds, Projects and packages")
Reducing the update interval will also affect cpu utilisation and so affect performance of router btw. LuCI is cpu intensive.
