View 6 Replies View RelatedI have newly deployed network. I have two ASA5520-AIP20-k9. both connected to ISP and configured as Active/standby failover. the ASAs were working fine at first but later on, the internet connection becomes very slow. the ping reply i am getting from my next hop(ISP router) varies during the peak hour is some times in 2000 msec or above but during off hours, the ping reply time is 1 and 2 msec. when I directly connect my laptop to the link that comes from the ISP its ping reply is 1msec and 2msec. I thought the ping reply of the ASA5520 to the ISP gateway should be constant and should be 1 and 2 msec regardsless of the traffic passing through the firewall.

Once it does, it connect perfectly. This is very annoying because I do not have a lot of time anyway to work/play and when I do, it takes over an hour to find the router.Recently, I have been having HUGE lag spikes, constantly disconnecting from games and skype calls.

The TL-MR3220 takes a long time to identify the 3g modem and sometimes it will not identify it at all and says "unplugged". Sometimes "unplugged" suddenly apears after the modem has been identified and was working properly.Is this the normal behavior of this device ? Why ? What can be done ? I'm Using Alcatel X500D 3g modem.
I have an Inspiron 1521 and while I can find and connect to a network easily and quickly; it takes 5 minutes or so for it to really work. My icon says it's "identifying the network". Is there anything I can do to speed up this process?

my ea3500 has problems with youtube videos. When i click to start a video, sometimes it starts but after a very long buffering time (more than 8-10 seconds), sometimes it does-not at all some other time, the advertisement play but nothing happens after that (black screen). I have a fast internet access (30 MB up, 2 Mb down). I do not have this problem with the old router that the ea3500 is replacing ( a netgear wndr3700). On this old router al the videos are starting almost instantly.
I tried to lower the MTU of the 3500 from the default 1500 to 1400. No improvement. I tried to disable the WMM feature in QOS and by doing so i create another problem : i cannot access the 5 Ghz band anymore. I can see the SSID but cannot connect to it.
Switch is a Nortel 5520
PC is Windows 7, with Intel 82579LM adapter
When PC was first attached to network, it could not ping gateway(switch). Turns out it was broadcasting for the gateway's MAC address, but never got a response. Tonnes of testing later, if I just change one number on the MAC address of the adapter, it receives a reply from the switch and can ping the gateway.
Why doesn't the native MAC address work?
Update: Just the vendor portion is the determining factor. As long as it starts with 2C-59-E5, it will not work. 2C-58-E5 will.
Update 2: Pinging anything in the same subnet works, just pinging the gateway interface of the switch doesn't happen. Tried on multiple drops, and there are other devices on those drops.
I know there has already been a couple of threads on this but rather than add my question to the bottom of one of those I thought I would try afresh.
We have an 857W connected to the internet via ADSL. All works very well, however if I ping from an attached PC the first one always times out. If i ping from the router (ping { URL}source 192.168.18.1) I get !!!!! every time. Back to the PC and 'Request timed out' on the first.
The only way I have been able to resolve this is by using no ip cef. It then works as expected, first ping and all. The problem is after much reading, it is not ideal to disable cef.
I have an issue that websites take a few seconds before they start loading, despite about 20Mbps download speeds.I've traced the problem to my E3200: when I ping a website, the first ping times out and only subsequent pings return. If I immediately ping the website again then everything is fine. After a few minutes the problem would resurface (per the specific website). This does NOT happen when I connect directly to my cable modem. This does happen both from wired and wireless devices. Happens on both Mac and Windows.

View 3 Replies View RelatedI am running a Linksys WRT54G wireless router but have my primary computer hard wired to it while my laptop connects wirelessly. In both cases, when I ping my IP's speed test site, I get a solid ping rate of approximately 17-20ms but i also get about 5% failed: timeout's. Now I've seen posts here that suggest wireless interference could be an issue but since my desktop is hardwired into the router, that source would seem to have been eliminated. When I connect my desktop direct to the cable modem the problem doesn't occur.
View 2 Replies View RelatedI have been though the setup a couple of time with no luck pinging one pc to another from vlan 10 to vlan 20. I posted the running configs and some other information from my router and switch. I am relatively new to all of this so if you need me to post more information from the hardware let me know and Ill put it up. There are no firewalls in place and I know the cables are good because I switched them around to make sure. Also when I change the ip on my second machine for vlan 10 I can ping from one pc to the other but when I try the same for vlan 20 I get nothing.

I have an Cisco EA2700 router and a Motorola SB6121 modem. If I'm connected to the router wirelessly or through any of the lan ports, I can't visit the modem's diagnostics page at 192.168.100.1. If I connect directly to the modem, it works fine. Also I cannot ping the modem through the router, just get a timeout. My ISP is Comcast.

View 5 Replies View RelatedI purchased and set-up the EA4500 on Thursday. Friday my ISP (Charter) was out and worked on connection for over 2 hours due to slowness issues. Connected directly to modem I get normal ping times on whichever computer is connected. When I get the computer connected by the router (hard wired) I get very long ping responses up to 900ms. They are all over the place 30ms (I can live with that), up to the 900's. I contacted Linksys support last night, who had me update to the cloud firmware and change MT U to 1300, have not noticed a difference. I did end up doing a hard reset on the router last night after I lost tech support. We were disconnected with router rebooted, and I didn't have the patience to connect again last night.
It was so slow on my work computer, a pint to yahoo timed out. The computers connecting to router are

View 17 Replies View RelatedAt home I have a perfectly working test setup for more than 1 year now , but yesterday we had a power down for about 10 minutes in the whole area , after this power down nothing was working in my network any longer.
My Network is has follow :
ISP(Cable Modem) on FA23 from the CISCO 2950 SWITCH (24 Ports)
ROUTER (ON A STICK) on FA24 from the CISCO 2950 SWITCH
And the rest of the switch is FA1=VLAN 1; FA2=VLAN 2;FA10=VLAN 10
Our home network is connected to VLAN 10 with a IP Range of 192.168.10.x /24 After this power down , I was not able to look into the SWITCH via FA1 , the FIX IP in this switch was 192.168.1.251/24, the ONLY way to get access was via the consol port !!!What a suprice when I connected my consol to the PC , I can see ROUTER_F342 , my router config is called ROUTER1841 and my switch config name is /was called SW24.So it seems that after this Power Down , the router took or received a config from my provider ?!?
I have recovered the the file in the switch + the vlan.dat and now everithing works again.
How can I avoid that this switch receive again a wrong file , I have all the needed files on the products itself and I do not use a TFTP server.
I have atached some screen shot when my switch is starting up , and it seems that the switch receive a IP address from my ISP , I do not know why, in the config file I have given it a FIX IP 192.168.1.251/24 ?!?So it seems that my ISP erase the config file and when the switch is empty ,the swich look for :
tftp://255.255.255.255/router-confg
tftp://255.255.255.255/ciscortr.cfg
Etc ....
Until it find something.
I have tried after a complete recovery to switch off the power again for 10 minutes (ISP MODEM + SWITCH + ROUTER) and I was not able to reproduce the fault.Can it be that due to this power failure in our area that some routers or switches send or broadcast this kind of things ?
