I am very disappointed of this product. I have tested everything.My 5Ghz is not working because the extender is giving the channels between 100 and 140.My devices can't support that.I have testet everything and I have latest fireware.I can't change it manually to 36.My router channel is 36.. But the extender does not follow my router.Please help

What is the point of "not" working here? hassaninho wrote:The settings on my router for high frequency is disabled.This is not Netgear's problem - convinced the extender is able to use this router wireless for linking the extender to the router, isn't it? hassaninho wrote:I use only 36-64 MHz channels on my routerThis does not affect any extender operation. hassaninho wrote:The problem is that your extender does convert the 36 to 100-140It's not "our" extender - most people participating are not working on behalf of Netgear. It does not "convert" anything - these modern extenders are wireless bridge with three radio interfaces, one 2.4 GHz, two 5 GHz. One of the two 5 GHz is used to establish the connection to the router wireless radios.Wireless extenders are not something "simple" like a bi-directional radio amplifier as installed eg. in road tunnels for FM/DAB coverage. These modern extenders have multiple radios, to avoid interferences due to near channels transmitters and receivers, they offer using different channel sets for the extender access point radios. There is no problem with this in general - these channels are prefectly legal to use in Europe (except e.g. Russia). What is the "real" problem now?Granted: Some old-old 5 GHz devices might not support the high channels, some IoT junk might have the similar problems. But that's nothing Netgear or any other extender vendor can change. hassaninho wrote:I want the extender do have it 36-64.When you think about the fact that a modern wireless device on the 802.11ac or 802.11ax standards does use 80 MHz (or up to 160 MHz bandwidth - that would occupy all channels 36-64!) on the 5 GHz band, the idea to re-purpose the same channels is a bad idea from the performance prospective Needless to say, that basic extenders do this - that's OK for low toe medium bandwidth requirements, but not for todays bandwidth and performance hungry wireless devices and users.Please re-think why you think you want this bad approach... hassaninho wrote:Ok but how does the 2.4 working.? It's also already used but the extender used same channel.The extender has only one 2.4 GHz radio interface, so the same channels must be used for the uplink to the router 2.4 GHz and for the extender access point radio.

Good in the aspect that it does share the same channels and the same 5 GHz radio for the router uplink and the local AP.... Not sure you have read and understood the differences shown above. I'm still trying to understand what the problem should be that the EX7500 does make use of different channels in your mind...

Are you running in access point mode or in extender mode?Are those channels grayed out or whats preventing the change? What is the latest firmware you're using? A number is better than "the latest"Which region are you in? and which region is your router and extender set to?

1. Extender Mode.2. No, they are not even on the list of 5ghz. I can only choose 100 to 140 on that list.My routers channel for 5ghz is 36 but the netgear extender change it to 100 - 1403. 1.0.0.524. Europe

For testing, if you enable access point mode (direct wire it), are you able to choose 32-48?What do you mean that your extender changes it to 100-140? It changes your primary router's broadcast channel?
