Prosim Vas vedel by niekto poradit ci su tieto zaznamy v poriadku?mam pripojenie na net cez kabel na router udava rychlost 1000 mb stahovanie -1,4mb/s ale stranky otvara 100kb

ten zaznam :# IPv6 Privacy Extensions (RFC 4941) # --- # IPv6 typically uses a device's MAC address when choosing an IPv6 address # to use in autoconfiguration. Privacy extensions allow using a randomly # generated IPv6 address, which increases privacy. # # Acceptable values: # 0 - don’t use privacy extensions. # 1 - generate privacy addresses # 2 - prefer privacy addresses and use them over the normal addresses. net.ipv6.conf.all.use_tempaddr = 2 net.ipv6.conf.default.use_tempaddr = 2

Zdravím,
oněch 1000 Mbps je zřejmě "fyzická rychlost" k prvnímu stroji (mezi počítačem a routerem).
IP adresy v obrázku jsou uvedeny jen IPv4, pokud má vše ze sysctl.conf skutečně hash (ten křížek), tak to není aktivní.
Pokud jde "blbě" internet, zkuste a) ping -c 200 -s 1200 8.8.8.8 (čili poslat 200x ping o velikosti 1200 bajtů na google), pokud to bude bez chyb, prověřte si tu stránku, kam jdete, co na ní vše je plus zkuste taky pingat na něco z ní.
Případně zkuste nějaký test rychlosti (rychlost.cz, https://www.lupa.cz/nastroje/speedmeter/, http://speedtest.cesnet.cz/).
