JNR3000: Wired speed fine, Wireless slow download & fast upload
Hi all, Since a couple of weeks I've noticed my Netgear JNR3000, the second router in the household, puts through extremely low download speed but decent upload speed when connected through WiFi; Speedtest gives 0.6 Mbps download, 18 Mbps upload, whereas the wired Speedtest shows 30Mbps/29Mbps as it should. I found these results when there was no other device connected to any of my routers. Also tested with multiple smartphones and laptops. The wireless results are the same everywhere throughout the house, even next to the JNR3000. The router uses the 'latest' firmware (V1.1.0.29_1.0.1), DHCP is activated (192.168.3.x where Router1 operates on 192.168.2.x) and the WiFi security settings are set to WPA2-PSK [AES]. Channel is currently set to Auto and Mode is set to 300Mbps. See the extremely detailed schematic overview below. I've already tried the basic stuff after browsing this forum; a hard reset (30-30-30), changing channels (most importantly a different channel than Router1 operates on, but evading other channels used in the area as well), disabling 20/40Mhz coexistence, Disabling QoS, disabling WMM, Fragmentation Length and CTS/RTS threshold set to 2342, switching Preamble mode to Short (from Long), RIP Direction set to Both and RIP Version set to 1 (although I really don't know what the optimal RIP settings are in this setup), disabling Guest mode (which is activated from time to time), making sure no microwaves etc. are near. Is there any chance of getting back to decent WiFi speeds (such as 20Mbps/20Mbps as it used to be) or is it time to replace my JNR3000? Are there hidden settings in Router1 (Arcadyan VGV7519 aka Experia Box v8) that forbid the JNR3000 from using maximum download speed when connected to WiFi? Thanks in advance, AlexLB1120 SLOW SPEED WITH ATT SIM
This is my 3rd LB1120 modem. I first install was 2 at work off a Sonicwall, for fail over connection. They had slow download speed at first of 5mbps down. Yet my cell phone was getting 28mbps down in the same spot. Both on ATT, but different bills. ATT try saying modem couldn't reach the 4G lte tower. And I was in a 3G area and that was the best they could do. So they did get fixed by a installer of wireless modems. Something on the ATT side. Well my 3rd LB1120 is for me. And max download is .5-3mbps. And now my phone is getting about the same speeds. Its like add the Netgear LB1120 trigger something in my ATT account that slowed my data plan down. I was getting 16 to 30mbps at home before the new sim card was turn on. Anyone ever have this happen? I'm on the 2nd week of phone tag with ATT support. 5 new sim cards between my phone and modem.
