problem s modemem

Recommended Posts

Mam modem Motorola SB 5101E, poskytovatel UPC, lokalita Praha. Nejde se pripojit.

Problem je ten, ze i po restartu u modemu sviti Power, receive, blika send, PCactivy,

 

downstream: 130 000 000 Hz

signal noise 39,9 dB

power level: 6,4 dB

 

Upstream: Channel 8

Frequency 23,2 MHz

power level 15,2 dB

 

S tim, z epo restartu modemu mi to hodi u Upstreamu uplne jiny numera, Channel 12, Freq. 50,8 MHz, power 28,2 dB

Z rozdvojky mi vede jeden kabel do televize a druhej do netu. Zkusil jsem privodni kabel pripojit primo do modemu, ale zadna zmena. Jde nejak zjistit, jestli je chyba v modemu, nebo v kabelu? Myslim, ze kabelem, enbo kontaktem to nebude, prekontroloval jsem ho, i kdyz jsem si konektor musel nasazovat sam. Jde zjistit nejakym programem, ze modem je OK? JInak kabelova TV jede v pohode.

S modemem nic neudelas, maximalne muses pres manager sledovat zda se modem pokousi ladit - v prohlizeci davat refresh rychle za sebou (klavesa F5).

Muze tam, byt i nejake ruseni.

 

Kazdopadne ted uz nezbyva nez objednat technika UPC.

Jaké jsou "rozumné" hodnoty parametrů - SNR a úrovně signálu?
