How can i use DG834g v5 adsl router as 2nd access point

[Zeudomzz]

Can someone please guide me in setting up my old dg834gu as an access point because my main router does not have qos setting unlike this netgear router

   Huh?  What is your "my main router"?  What has QoS?

> [...] setting up my old dg834gu as an access point [...]

   My quick search found info on a DG834Gv5, but not a DG834GUv5
(Perhaps "U" denotes "with USB"?)

   In any case, QoS is a router feature, not a wireless-access-point
feature.  See:

   If you still want to configure your old DG834GUv5 as a WAP, then see, for
example:

That's written for a C6300-as-WAP, but the steps are about the same for
any other router (any make/model) which lacks a one-step WAP option.

My main router is LTE Router named Huawei B315s-938 which lacks QoS option unlike the netgear dg834gv5

The DG834g is a seriously old (2008) ADSL modem/router.

It will have few of the bells and whistles that come with newer devices.

You may be able to put this thing into AP mode, but doing so will almost certainly disable features such as QoS.

Disabled Features on the Router when set to AP Mode | Answer | NETGEAR Support

That KnowledgeBase piece is for devices that are designed to be used in AP mode, but I doubt if that will make much difference.

By the way, according to Netgear's manual for this device the LAN and WAN support only 10BASE-T or 100BASE-TX. That makes it slower than many newer internet services and most modern network hardware. This may not matter to you, but be warned that it will hobble you if you ever sign up for faster Internet. It also slows down whatever is going on in your local network. Newer devices support 1000BASE-TX.
