ı am just too tired.. ı am en electrical engineer so ı know about modems in general or behaviour of electricty and signals.

ı wish ı could say ı know nothing about networking or network aspect of computing and engineering but thanks to this router ı have been in forums and sites for 2 weeks!

ı am sorry.. ı am just too tired from this.. ı sent my device to my local tplink techical support they said it has nothing wrong with it but am ı crazy!!!!

.. sorry again 2 weeks of waiting fixing the agony is too much for me.. so ı wıll try to tell you my problem hopefully for the last time...

my modem (which is the provided by ısp) is fast with my pc both with wired and with wireless aprox. 30~~25mbps

but oh boy when ı try to connect to my archer ax55 its not constant! it gets 14mbps for 2 secs then 660~~72 kbps for 10 or more secs sometimes ı load this forum in a second but sometimes (which was now) it took 1 minutes and 38 seconds to show me the buttons and assets of the site!

both wired and wireless has this problem ı formatted my pc for this for gods sake but no luck..

why is this interesting you say ? hmhmm allow me to eleborate

ı ran these tests with my phone solid 25~~30mbps!

with an ı pad ı get the same result

with an other android device ı get the same 25~~30mbps

ı bought this device for to use it with my quest2 and you guesd it it gets a solid 25~~30mbps too

in games ı cannot download anyting.. for example in vrchat it took me 14 minutes to download a 2.83 mb avatar... 14 minutes..

ı know ı know try another pc?

4 devices.. they are all the same.. for 2 secs they get 2~~~15 mbps but for 10 or more seconds they got 660~~72 kbps both wireless and wired connection.

and its not easy for me to find 4 windows devices and ı dont have any other house or ısp to test my router

ı am so confused... ı talked with my ısp and they sended a technician but no luck they found nothing wrong ı called tplink they got my device and they say nothing wrong..

what is wrong then.. please help me ı tried everything..

qos is not the problem tether app is not the problem my pc is not the problem ısp is not the problem cables are perfect cat6 and according to tplink's turkish support (which ı am stated at turkey) says my router is perfect!

what is wrong... ı can run any test ı can ı am ready for fixing this issue because apperantly nor tech support nor my ısp is willing to help me..

please ı am open to anything for 2 weeks its enough for me to stress and think hard over it

ı am sorry for my aproach if ı used any hard words or misspelled any words because english is not my native

thank you for reading this so far ı am waiting for a respond to make my day..

ı wish you have a good day
