No dobrze... ale może brak aktywnego huba USB? LTE zdaje się bierze więcej mocy niż 3G. To mogłoby tłumaczyć, dlaczego na PC LTE działa fajnie.

Odp: TL-MR3420: obciążenie 4G i problemy z pamięcią (?) (9 odpowiedzi, napisanych Oprogramowanie / Software)
No cóż,
najwyraźniej jest coś na rzeczy 
Zastanawiam się też nad 4300 - warto?
Jest jeszcze inna opcja - ostatnio wpadło mi w ręce takie urządzonko. Może najpierw nim się pobawię, skoro już je mam Wówczas TL spadnie do roli wifi AP tylko (tam tego nie ma).
W każdym razie dzięki za opinie, coś z tym fantem muszę zrobić.

Temat: TL-MR3420: obciążenie 4G i problemy z pamięcią (?) (9 odpowiedzi, napisanych Oprogramowanie / Software)
Problem jest następujący:
przy obciążeniu łącza 4G (modem E3276), download przez jakiś czas na poziomie 30-40Mbps pojawiają się błędy, związane chyba z przydziałem pamięci (całość poniżej). Problem jest o tyle dotkliwy, że dodatkowo często powoduje to reset Wifi (na chwilę się odłącza i znów podłącza). Po wywaleniu Gargoyle i zainstalowaniu czystego openwrt (aby zaoszczędzić trochę pamięci) problem objawia się faktycznie rzadziej i przy dłuższych downloadach. Tym nie mniej się objawia. Próbowałem też instalować dystrybucję huntsmana (tę z ofmodemsandmen) ona jest z trunka (Barrier Breaker) - tam było o tyle lepiej, że pojawiały się tylko błędy
cdc_ncm 1-1.2:1.1: wwan0: kevent 2 may have been droppedczyli bez dumpów, które są w AA i nie zrywało WIFI, a i dodatkowo ograniczał wypuszczanie tych ostrzeżeń o dropach (nie pamiętam tej funkcji, chodzi o to, że przy większej liczbie tych samych błędów logował tylko ich liczbę, a ta potrafiła być całkiem wysoka).
Wyraźnie widać, że powoduje przycinanie transferu (transfer drastycznie spada na jakiś czas). Być może nawet mógłbym osiągnąć więcej niż te 40MBps, ale router najwyraźniej nie pozwala .
Co może być przyczyną i jak można temu zaradzić? Podobny problem widziałem w innym wątku i dotyczył 1043 i wydawał się nierozstrzygnięty, oba routery mają 32MB pamięci RAM. Czy faktycznie sterownik cdc-ncm potrzebuje tyle pamięci przy większym obciążeniu i na tym routerze więcej po prostu nie wycisnę? Czy dołożenie swapa mogłoby pomóc?

Odp: Sprzedam modem LTE (6 odpowiedzi, napisanych Oprogramowanie / Software)
Jeśli używasz modemu stacjonarnie, to zanim sprzedasz, możesz rozważyć kierunkową zewnętrzną antenę (przypuszczam, że ten modem ma wyjścia antenowe, jeśli nie, to nie ma tematu). U mnie w domu zasięg jest beznadziejny, antena na kominie pozwala mi na łączenie z LTE z poziomem sygnału (dość stabilnym) na poziomie -70dBm, odległość od stacji bazowej to ca. 7.5km (albo 9.5km, dalszy, ale stoi wyżej, na skarpie, nie wiem, z którym się łączę, na btsearch.pl nie ma CI stacji LTE). Antena najlepiej dedykowana do LTE, najlepiej MIMO. Ja używam dualnej panelówki Cybertecha.

Odp: Modem LTE: sprawdzanie statusu przed nawiązaniem połaczenia (2 odpowiedzi, napisanych Oprogramowanie / Software)
No tak, monitor połączenia rzeczywiście z automatu nawiąże połączenie przy kolejnych iteracjach.
Ja go nie ustawiłem: sępię na pakietach 
4G jest u mnie jedynym oknem na świat, ruch ICMP wlicza się do limitu. Tak wiem, niewiele tego uzbiera się przez miesiąc, ale... A połączenie mam, odpukać, bardzo stabilne.

Temat: Modem LTE: sprawdzanie statusu przed nawiązaniem połaczenia (2 odpowiedzi, napisanych Oprogramowanie / Software)
Nie wiem, czy u Was też się to zdarza, ale u mnie po blackoutach praktycznie regułą jest, że router po wystartowaniu nie nawiązuje połączenia LTE (komenda w /etc/rc.local), tzn. myślę, że dotyczy to ogólnie 2/3/4G (modem e3276, router tp-link 3420v2). Wynika to z tego, że modem nie zdąży zarejestrować się w sieci jeszcze, a nawet jeszcze się nie przełączy (brak dev/ttyUSB0 wg logread). Problem nie występuje przy boocie samego routera, jako że modem jest połączony przez aktywny hub usb, a więc mając zasilanie (chyba?) nie gubi rejestracji, w każdym razie ten problem się nie objawia.
Aby temu zaradzić, dodałem następujący kod w /etc/rc.local, przed nawiązaniem połączenia:
# wait for modem registration
REG_STAT=0
while [ ${REG_STAT}x != 1x -a ${REG_STAT}x != 9x ]
do
REG_STAT=$(gcom -d /dev/ttyUSB0 -s /etc/gcom/checkregistration.gcom | grep '+CREG' | cut -f2 -d " " | cut -f2 -d,)
sleep 3
donecheckregistration.gcom to prosty skrypcik comgt robiący AT+CREG.
Drugie pole zwracane przez CREG to stan rejestracji. Zgodnie z 3GPP TS 27.007 interesują nas
1 registered, home network
9 registered for "CSFB not preferred", home network
(nie wiem, czy ten drugi status faktycznie może się pojawić, ale CS fallback chyba jest przez opów wspierany).
Ew. może jeszcze registered in roaming (5, ew. 10).
U mnie działa, może się komuś przyda.
A może o czymś podczas konfiguracji zapomniałem i dlatego nie działało?

Tak, działa poprawnie.
Dzięki!

Co prawda temat trochę stary, ale pozwolę sobie uzupełnić:
wydaje się, że problemem są spacje pomiędzy ustawieniami trybu CREG a wyświetlaniem informacji:
AT+CREG=2; +CREG?
ERROR
AT+CREG=2;+CREG?
+CREG: 2,1,"BF6B","2D01"
OK
To samo dotyczy COPS.
Po małej modyfikacji skryptu /usr/share/3ginfo/scripts/3ginfo.com wynik komendy 3ginfo:
root@upupa:~# 3ginfo
Status: Brak informacji
Czas polaczenia: -
Przeslano danych: - / -
Operator: Plus
Tryb pracy: LTE
Sila sygnalu: 64%
Urzadzenie: huawei E3276
MCC MNC: 260 01
LAC: BF6B (49003)
LCID: - (-)
RNC: - (-)
CID: 2D01 (11521)
CSQ: 20
RSSI: -73 dBm
Jeszcze coś by tam trzebaby w samym skrypcie 3ginfo poprawić, by prawidłowo wyświetlał czas połączenia chyba.
Pozdrawiam,
Bubu
